Sefi mixed and mastered my song, and it sounds so beautiful! I absolutely love how I mixed and mastered it!

Always a pleasure working with Sefi . . . great ears, killer sound and he adds that little touch of magic, so hard to define, but when you take it away, something is missing.... so you just gotta have it. Highest recommendation.

It is always a pleasure to work with Sefi, he has amazing intuition when it comes to knowing just how to bring the best out in an artist, enhancing and elevating the work.

Needed a string arrangement for my song and Sefi delivered in spades, the sound quality was top notch and his ear for crafting a memorable yet highly original piece is world class..amazing! It has taken my track to a new level. Sefi is a true professional and can provide outstanding results.. I will definitely be working with him again. Highly recommended

Great working with Sefi for the second time and looking forward to the next project!

Sefi has produced two tracks for me and I could not be more satisfied with the results. My songs are not easily categorized but Sefi is a great communicator and got the vibe immediately. He enhanced the elements I was already happy with, and more importantly he truly supercharged each track overall and gave superb input and ideas. Powerful & groovy, yet atmospheric & emotional. He also delivers the first draft before you even know it. Sending more tracks to him ASAP! Highly recommended.

A true pro, love working with him. Look forward to next project! Thanks again.

Once again Sefi Carmel has proven to be a top-notch pro, I consider myself to be a pro and I love working with Sefi because he pushes me/music to the extreme limit's. Sefi listen with an open mind with no attitude, if you know what you wont then bring your "A" Game and he will deliver, Sefi also has a great ear for music, Top of the line pro audio gear, Most important he understand how to use it to get you that clean Radio/TV sound your looking for.
Thanks again Sefi, love my new track :O)

I am surprised at his work every time. it is really amazing.

Another great job from Sefi. Always a pleasure to work with and he always delivers an excellent quality mix and master.

Unreal sounding mix! Sefi is always very professional and accommodates all requests. Great job!

I wish I could give Sefi 10 stars! Not only is he extremely professional and pleasant to work with, but he has also always mixed and mastered my songs to superb quality and always has my best interest in mind.

another excellent mix/master. always impresses me with the superb sound and an even better person.

It´s such a great opportunity to work with Sefi together!!! It doesn't´t matter if producing, mixing or mastering - Sefi always creates a big sound miracle!!!

Sefi is the man. He was quick, and super easy to work with!

Class, style, appropriate and totally cool... can't get better than that!

It was a truly incredible experience to work with Sefi, who delivered a song above and beyond all expectations. Sefi's kind and supportive manner makes him not only a pleasure to work with but also a true professional. I am honoured to have had this opportunity.

Great work! This new remix sounds absolutely great, thank you, Sefi!!!

A master at his craft and will go above and beyond! Took my mix from 60% to 100% in no time.

Sefi has become my safe harbour for mixing and mastering my work. Delivers the perfection and always a pleasure to work with.

It was a pleasure to work with, Sefi. Communication was smooth, and so was the final product. Highly recommend!

It is an absolute pleasure working with Sefi. Communication was easy and prompt. He delivered to my expectations and more. I am completely satisfied and can't wait to send more tracks for mixing and mastering

Couldn’t be happier with the first project with Sefi. Technically and creatively he took my song to a place I could only have hoped for. He created a soundscape that is as contemporary as tomorrow, yet kept my love of darker 80s synthbands and created a unique sound I am thoroughly satisfied with (as is everyone have played it for). Prepping 3 more tracks to send to Sefi. On top of the actual work produced, he’s an exemplary communicator. Easy 5 stars. Can’t wait to work on more tracks.

Sefi did masterful work incorporating new low end string sections into my song. He's able to blend VST libraries with live performances seamlessly. I'm very excited to present this to the world.

Great master, incredible sound, excellent ideas - I´m so happy!!! Once again, it was a big pleasure for me to work with Sefi together. Can´t wait to start the new project!

Once again, brilliant work! Thank you, Sefi!

Sefi did an amazing job mastering my song "I can see the sun". I have worked with him a lot for my upcoming album and he always delivers amazing mixes as well as mastering. Highly recommended!

Sefi has been nothing short of amazing. Fast, reliable and extremely patient. The process of working apart and through emails can be quite frustrating in my opinion but he made sure that it was as smooth as possible. I would recommend him to anyone looking for that "radio ready" sound!

Sefi takes my music to the next level and beyond with his mixes and masterings. He was able to integrate additional contrabass into an old mix flawlessly. The final product is balanced on all levels and sounding exactly how I want it to.

Working with Sefi was a wonderful experience. I am new to having someone mix and master for me and he was very patient with me. He has a wonderful attitude and you can tell he really takes care of your song as it is his own. The song sound quality is extraordinary and I highly recommend Sefi Carmel!

This was the first project I worked with Sefi on and I must say I wasn't disappointed. Sefi is a true professional, very patient with edits I requested and made the changes exactly how I wanted. He understood exactly how I wanted the track to stand out and made the track into a "smash hit!" I look forward to working with him again on future projects.

Incredible well done mix, very responsive and did all we asked, very detailed a pleasure to work with!

once again, Sefi mixed and mastered a track for me and made it sound way better than I thought it could have been. His skills are insane and the creative effects he uses blows me away every time. if you want superb, high quality, radio standard mixes, you should use Sefi. Trust me!

C'est toujours un plaisir de travailler avec Sefi. Il est disponible, efficace et très talentueux.

Sefi performed seamless editing on a few cello tracks and was able to piece together for me two organic sounding perfect takes, which he incorporated flawlessly into a new mix. He's one of the very few engineers I'd trust with such fine tuning finesse.

Sefi is incredibly talented and a top-notch professional. The creativity, care, and attention to detail with which he approached my song really took it to the next level, and I love it! I'm already working with Sefi on another project and encourage you to do the same!

I now have an expert engineer and pair of ears. No one in Los Angeles can mix orchestration/music like Sefi! I am super happy with my mix.

So grateful that I came across Sefi’s profile. He has taken my first track ever to a whole new level with that studio magic that he does. He is very patient and will listen and make any changes that you suggest with no need for long explanations or further clarifications. It is clear that he understands the needs of a musician and is very responsive at all times which is super helpful.

Thank you Sefi and look forward to working on future projects together!

Many words no needed - Sefi is a Genius and PRO engineer. All other our tracks will be mixed and mastered by Mr. Sefi. If you want to be the best - you should work with the best.

Sefi took a fantastic violin solo and made it legendary with flawless editing.

I really enjoyed working with Sefi. He made everything super easy and completely understood what I was looking for. I asked a lot for the song and he was able to take all my notes and turn my song into a song I love. He was super fast in getting the different takes back to me. I will definitely have to work with him again in the future.

Second great mix & mastering i did with Sefi. Very, proffesional, skilled & patient person that will never let you leave unsatisfied. Great guy!

Really liked Sefi. He was super accommodating, no matter what I threw at him he digested it and produced it from instructions like we need part X to sound more bell like or we need the guitar to have the bit more of the British Marshall numminess to add waves plug in XYZ to measures 26 - 47 with settings ABC and that is the sound we are going for in that part. He seemed to really understand. Can't wait to use him on my new song with a synth part :) I bet he will blow it out of the water :)

Sefi is the man. Takes feedback and implements it without any clarification needed. Really took the time understand the vision on my project!

I will make it simple! IGreat guy, great mixing engineer. Great skills & feeling for music! It was a pleasure to work with him!

Sefi add exactly what our song needed, i definitly recommend if you need top class mastering for your songs !

Working with Sefi couldn't have been better. He worked very quickly and with precision, understanding the sound of my songs completely and bringing out the best in them. Brilliant.

This is the second song Sefi has mastered for us and lets just say its easier for you to work with him and judge; because you won't be disappointed.

Sefi is very professional and live up to his reputation (years of experience). High quality music was produced, he went the extra mile and even shared knowledge with us in areas he didn't even have to. I can tell by his patience he does this because he loves it (not just for the money).

Friendly. Approachable. Respectful. Quality Work.

What an amazing producer and person. Thanks for yet another great production Sefi.

Best regards
Avi

Once again, thank you so much, Sefi! I really enjoy the sound after the mastering! Superb!

Worked second time for mastering a set of Indian classical songs. Great work. Sefi is very accommodating and welcoming towards any feedback. Pleasure working with him and received high quality mastered songs.

A pleasure as always! Mix sounds badass

Sefi killed it, enough said.

Sefi took numerous takes of an almost impossible cello solo and blended them seamlessly into three perfect layered performances. My session player sounds like Yo Yo Ma now. Sefi will deliver for you a world class mix and master of your song. He also charges reasonable rates for revisions and can pick up right where he left off with a song if you have an improved performance you want to switch out at some point.

Sefi was able to splice in a replacement clip for a very vest violin solo played on a different amp than the original performance with absolute surgical precision. When perfection is the goal, Sefi is a rare engineer that can facilitate you getting across that finish line.

It was great working with Sefi again, very professional and delivers high quality masters. I would definitely be coming back to work with him again.

Sefi was excellent. Flexible, timely, and professional. His mix is crisp and sounds good on everything from Bluetooth headphones to a nice stereo system. Will hire again.

Once again, it´s a great pleasure for me to work with Sefi together. He takes an average sounding track and turns it into a hit with a chart topping potential. Sefi thinks about every tiny detail, creating an incredible sound. Great musician!!!

I've had the pleasure of working with Sefi Carmel for the entire process of mixing and mastering my forthcoming album. His work has been of the highest quality and his technical and creative input has greatly enhanced the sound of all 14 tracks. Sefi is a true professional, a very good listener and always accommodating and helpful. Above all, he's a master sound engineer with the ability to add that critical extra dimension to the music. I wholeheartedly recommend his services.

Sefi, it's just awesome.
A great talent. The songs sound great.
Easy and effective communication.

Sefi was able to seamlessly edit in some new violin clips and tune them to perfection! His very timely delivery is much appreciated. When you work with Sefi, you're working with one of the best of the best.

Sefi is a fantastic engineer with an extremely experienced ear. I've worked with him a few times before and it has always been a pleasure - friendly, professional and great judgement. I'll be back.

Sefi has mixed my debut album consisting of 10 songs. I was actually over to Sefi at his studio outside London recording lead vocals earlier this year. He and his staff were very friendly and professional. They took us to a very nice restaurant at the very last day to celebrate the work done.

I would highly recommend Sefi as his mixes are world-class. I have tried a few top mixing engineers and Sefi is up there at the very top.

Highly recommended!

Sefi is an awesome professional. His sound is top notch. I sent him a home studio demo and he immediately created a professional version of it with excellent production and sound. Throughout the process of the project any feedback I sent to him he understood and applied with no further clarifications asked. Ιt is clear he knows music and has an excellent perception. Thank you, Sefi, looking forward to working with you again!
Apollo Matrixx

It was a great pleasure working with Sefi. He was able to interpret exactly what I wanted and when I requested any changes he made them with no fuss. All very effortless and a great experience!

Excellent Producer, very talented. We made a awesome song together. it was a pleasure working with Sefi again.

Always excellent work!

Great work! Very nice guy and I super happy with the mix.

Well, I see the reason Sefi has so many good reviews. He did a great job on my tracks, and met all the deadlines. I was concerned because this piece was a slow, moody ballad and he doesn't have a lot of samples of those. But he rose to the challenge and laid down some lovely string and piano parts that were wistful, moody, and dark that really elevated the song. I'd use him again.

Sefi is a great guy to work with. Very professional and quick at responding to my questions whenever i ask for something. Most importantly, he delivers great mixes/masters!

Sefi did a superb mastering for me, once again. Get's the job done in time, and it sounds great! Thanks.

Always great to work with Sefi!
My music couldn't be in better hands!

It was a pleasure & extremely satisfying experience working with Sefi who's a seasoned artist. We had an Indian Bollywood song recorded already; for which he produced music, mixed & mastered - to top notch quality and absolute perfection.
With his enormous patience, sharp understanding and responsiveness, it was easy to work with him & communicate ideas. A thorough professional, he is very courteous too. We enjoyed working with him & highly recommend him if you want thee Highest Standard.

Sefi responds and works so quickly! He’s also very polite and honest in his assessments. I enjoyed working with him very much.

Really a pleasure to work with.
He is patient and kind.
The product that he produces is top notch!
I would definitely recommend working with him!

I am beyond thankful that I found this legend, Sefi. He is a true professional who has done so much work for me and mixed my debut album. I've worked with many engineers, but this is very different. He has endless patience, creativity, and an amazing personality. If you need mixing of the highest quality, I give my highest recommendation.

Sefi gave me an incredible bargain: a complete soup to nuts remix with mostly new and improved instrument tracks for only $200 and it sounds incredible now!

Excellent mix and master!! Took my track to a whole new level!!

I am so happy I started working with Sefi. Perfect sounding mixes and mastering. Very professional sound in combination with the most friendly and patient person, cannot go wrong!

An absolute pleasure to work with. Sefi is one of the most polite, professional engineers I've worked with thus far. Was willing to go the extra mile to make sure every little detail I wanted was accounted for. Although we didn't nail it on the first mix, Sefi worked with me and got the mix EXACTLY the way I wanted it. Would definitely recommend. In case you haven't seen it, Sefi Carmel has an episode with Spitfire Audio that you should totally check out to get a glimpse in his badass studio

You couldn't ask for better!
My track came back sounding beautiful!

Great experience working with Sefi, very professional , punctual and easy to work with. Will surely be coming back for future projects.

Sefi has proven himself to not only be a legendary mixing engineer, but a masterful mastering engineer as well. He had the unenviable job of mixing single acoustic guitar parts over entire orchestral string sections - something that just isn't done because it's nearly impossible to get those sections to sound good together, but it all sounds absolutely terrific now thanks to Sefi.

He makes the process as smooth as possible!
Super professional and communicative at every step!
The track sounds awesome!

Fantastic mastering-results, and i'd love to work with Sefi again.

If you are not 100% certain about your mix, I suggest that you ask someone that lets you re-adjust your mix and send back if any problems are more noticeable after mastering. That has given me great results earlier, without much extra cost. So this one is a litte pricier than anything before, but I am happy with how it turned out.

Very much enjoyed working with Sefi and his team when recording vocals at his studio outside London. Everyone was very professional and working hard to get great results.

Highly recommended!

Sefi delivers the most amazing mixes with incredible patience and constant communication that just makes the whole process so easy and straightforward.

I'm so honored to have worked with Sefi. He's very timely and professional. He really took the songs to the next level.

Sefi really came through with a very time sensitive project. Best review I can give is to refer you to my upcoming album Arranged Accidents, where he did the mixing for four of the songs. I can go out and promote these songs with 100% confidence because the mixing quality is so high.

Fantastic experience as usual. I always enjoy Sefi's professionalism, knowledge, and demeanor. He makes the job, no matter how intricate, feel like a breeze. I am lucky to have teamed up with him. Thanks Sefi!

This guy is a genius, that says it all!

Sefi does a insanely good job at mixing and mastering! I can’t explain how good he is at what he does!

The mix I just got back from Sefi sounds EXACTLY the way the song sounds in my head.

This guy will give you 5-star tar version of your song! Love what Sefi can do to your song!

Yet another amazing vocal edit/mix done by Sefi, I can't stress enough how good he is at his work. Everything that I have received on multiple songs sound lush, expensive, clean and professional. He is an amazing person to work with as well, very quick responses and turnaround. What more to ask for? Thank you Sefi!

Its been a pleasure working with Sefi on a number of songs now, always professional and amazing sounding tracks. Thank you!!

Once again Sefi delivers 10 out of 10 work! He has helped me fully realize my vision for several pivotal songs on my upcoming album, Arranged Accidents.

Working with Sefi has been amazing throughout the entire prosess! He is utterly professional, and goes that extra mile to get you exactly what you want. The mixes sound absolutely brilliant and his ability to understand your visions are outstanding. When you add his positivity and patience the experience is simply the best I could hope for. I highly recommend Sefi, and will never have my music mixed by anybody else in the future.I'm forever greatful for a wonderful experience with my first album

It's was very amazing working with Sefi.

Sefi made the songs sound so much better with his skills! Absolutely a pleasure working with Sefi!

Sefi produced, mixed and mastered my track and made it shine. Ab-so-lu-te top class!

Yet another professional awesome vocal mix by Sefi! Highly recommended!

Beautifully tuned and edited vocals, amazing work again! Thanks Sefi 5 stars

Sefi edited and tuned my vocals perfectly! Really professional and amazing sounding job, extremely fast and instant responses to my messages. Thank you! 5 stars

This was my second Mix/Master job with Sefi, and definitely not my last one with him. Excellent skill, communication and delivery.

Highly professional perfectionist. Prompt & precise. Loved working with him.

Working with Sefi has been a pleasure, never complaining for revisiting a mix, producing files. The tracks were mixed and mastered superbly, amplifying the mood and spirit in which the songs were written. Sefi has taken my music to the level I was looking for. He is beyond any doubt a very high valued extra member of the band.

Sefi has done a wonderful job mastering my track! Very professional and easy to work with!

Self did a great job on Bantunani's new single, he did understood exactly this very special groove and gave it warm and fresh feelings.

Sefi is a professional who has the experience and know-how to get the job done. My band now uses his services exclusively for our mastering needs.
In short, he will deliver mixes that are objectively loud and bright all without compromising on the dynamic of the tracks. I also recommend his mix critique services prior to mastering.

Sefi Carmel is an amazing mix engineer! Everything was professionally and promptly handled! I highly recommend him to anyone looking for a great mix!

Sefi did a fantastic mix and master of my track! I couldn't be happier with the service. I highly recommend :)

It was a pleasure working with Sefi. A true professional who made a great mix & master. Quick response and very easy to work with. I highly recommend working with this man. Awesome experience, definitely 5 stars!

Sefi will give you an excellent mix up front, and then completely knock it out of the park with the first revision. This last song has perfect panning, depth, and dynamic fader levels for each track, giving each instrument space to breathe and be heard in the piece.

Superb attention to detail, good musicianship and excellent ears. Solid communication throughout the process. I would highly recommend

thank you for your very good mix - Très belle sensibilité artistique - We look forward to work with you again.

As always Sefi is on point and professional in every way.

Where do I find the 10-stars-rating? Working with Sefi - and I mean WORKING, as in colab, coop, cothink and co-have-fun - is a pleasure, an honor and a privilege. That said: Sefi made this song work from almost zero to something I just love.

Sefi has been very professional and delivered the mix in time. He delivers world-class mixes that sound very good. He reacted promptly and professional to my mix feedbacks. Highly recommended!

Amazing producer, very talented. I loved how he worked on my song. Helped me a lot.

Sefi is a brilliant musician. He feels music and sound with his heart of a great professional. I´m always happy to work together with him.

Such a talented producer and a real pleasure to work with! Keeps going until client is satisfied.

Great guy to work with ... very accommodating. Professional results.

Sefi gave me a world class mix that I would be proud to present, as is, for sales and sync licensing. He does mastering too, which was an unexpected bonus. His outstanding use of pan control allowed me to hear all of my many individual orchestral parts clearly.

Amazing sounding mix! Very responsive and easy to work with! Can’t wait to work with him again.

Sefi is a pleasure to work with in all aspects, a total professional. The sound and cohesiveness he delivered on the mastering of my album is top notch and his attention to detail was inspiring. Thank you sir, highly recommended!

This was my first project, and it was very uneventful. Despite my endless requests, Sefi Carmel gave his all without a single complaint. I have learned a lot from one of the very best, who despite his busy schedules found time to maintain great communication. We will definitely work together again.

Sefi was very good to be in dialog with me. always fast respond and he didn't stop until I was 100 % happy with the song.
he gave me advice, guidance and everything I needed to be happy with my song.
an absolute pleasure working with him.

Sefi Carmel went to the edge of the world and back to make my mix top quality and ready, building a mountain beyond what was expected. He repaired all of my weirdness, well, not all, I still have some, but he wrangled my vocals and delicately managed the harmonies, subtleties and symphonies to form a perfect soup. Sefi is the best.

Sefi is amazing to work with. This is my second song with him. Thank you Sefi for another wonderful job.

Sefi has been impressively patient, responsive to whatever weird idea I came up with, helpful and imaginative to get our first cooperation turn out the way I wanted it to be.

Sefi is an incredible talent. Superb attention to detail. Great ear. Perfectionist. I will be using him again for my next single. Can't say enough how fantastic of a job he did on my song.

Sefi, thank you so much, once again, for your incredible art to reshape music to the new hit. I´m always happy to know that the new miracle comes my way soon, as you start to work on my tracks. Looking forward to work together on all the new projects we´ve planned, and - thank you!!!!!!!!

Sefi is a great music producer. I gave him a challenging task of producing a Bollywood song; music has no boundaries. Language or region. Sefi proved that when he produced my song in the best possible way. I am so happy with the way the song sounds and can't wait to share it with the world. Thank you Sefi!

Having hired Sefi for mixing and mastering nine of my tracks so far, I am pleased to note that the results have been truly stunning. The quality of his work has been exceptional so I look very much forward to continuing our collaboration. Based on this experience I wholeheartedly endorse his services.

Sefi is a true professional and a pleasure to work with. My songs were brought to a new level and sound great! I'm OCD and he was easy to work with, that says a lot! You can hear the pride he takes in his work. Do yourself a favor and hire Sefi. I learned a great deal working with him. Looking forward to future collaborations.

Sefi did a great job. My project was a cello cover of a popular song. Sefi was patient and responsive through multiple iterations of the sound track until my satisfaction. Would highly recommend.

Thanks a lot for such a marvellous track! It has been a great experience to work with you!!will definitely come back for more👍☺

Great person to work with! He is really talented, well worth it and will make your track shine. He is a really nice guy and willing to listen to make it as sharp and awesome sounding as possible. I definitely recommend him!

This man did a fantastic job of mastering my song - sent him a mixed track and he sends me back a hit. You have my eternal gratitude, sire.

When I choose to work with Sefi, I had no doubt I will receive a Professional work, from a world class artist... but what I discover, is that he is also an incredible person, ready to listen, to understand what you want to say with your music and put that on his work. I am very happy from this experience and I hope I can work further with him.

I can not begin to express my respect and gratitude I feel for Sephi! He is simply the best mastering engineer on the planet! His unselfish giving and caring nature truly shines through! Hats off to Sephi! Can't wait until the next project!

Hiring Sefi was a great decision. He is musical, technical, patient, and attentive to detail. I also learned a great deal working with him. I definitely will be contacting Sefi for upcoming projects and would definitely recommend his services.

I have worked with about 20 producers so far, and I swear Sefi is the best! He comes with years of experience and I could see that in his work. He understands the artist and brings to the table a production quality that brings out the best in the song! He is a very patient and very humble human being! I am already working on my 2nd song with him!

Between his confidence and superb communication skills, i felt more musically secure than with anyone i have previously worked with. His ability to understand exactly what i was looking for, even through long distance communication is unbelievable. And believe me, "exactly" means exactly.
Def recommend!!!!
(stay tuned, i will post my release.)

Sefi is extremely talented and professional. He was glad to make a few tweeks to the project to make sure I was happy with the final product.

Truly a wizard behind the board.

We look forward to hearing his mastering take of our music while we're recording our score.

I would not shop around for other Mastering. Hire Sefi! but not too often because we want him to ourselves.

It´s a kind of magic... The sound of this master is brilliant!!! Thank you Sefi!!!

That's perfect, thank you

Sefi is sooooo on top of his game. Mad skills! Great mixer/engineer and very good turnaround time. Easy to work with and utterly professional. Great experience. So great, in fact, that I just asked for his help with 2 more tracks.

Sefi did an amazing job on our song! We couldn't be happier. He brought the song to the next level and added many great synthesiser sounds. He takes direction well and also is able to come up with his own ideas if asked to. We were able to work on it and make as many revisions as needed. Great guy to work with!

Sefi is an awesome producer! The tracks that he sends back sound of the highest quality. Everything about the sound of his mixes is professional level down to the last little detail. Just recently, with one my tracks, he took the recordings and basically set a benchmark for Shanghai's Heavy Metal music scene to follow. I highly recommend this guy

Sefi has delivered me exactly what he promised: wonderful sounds, powerful and perfectly fitting for my track. Thank you Sefi! Can't wait to work again with you in the future!

Sefi Carmel is a studio genius; he creates an amazing mix of amplifying your band's natural strengths, while incorporating his creative production ideas and techniques. His mastering quality is immaculate. Perhaps most important, Sefi takes the time to listen and understand client musical goals, and completely exceeds expectations. Thank you Sefi!

This guy took my broken song and turned it into a powerful heavy metal masterpiece. Everything was perfect from the drums to the vocals. The offer price seemed high at first, but it was absolutely worth the money in the end. All of my label's most important songs will go to this guy in the future. No questions asked.

Working with Sefi on my new remix has been fantastic, as usual! Extremely well mixed and mastered. Sefi perfectly understood what I had in mind! Thank You Sefi! Can't wait to work with him again in the future!

Don't think, just do. Sefi is a professional of the highest order. Friendly, positive, responsive to changes, punctual with communication, and keeps a perfect balance of injecting his own ideas and keeping the vibe you were going for originally. Took my tracks to a new level!

Sefi is AMAZING!! Very fast and talented!! Thanks man!
All the best

Sefi is fantastic.
