Our goal is to put a smile on artists' faces when they get to hear the final product by the quality of our production, mixing and mastering. Plus making it a collaborative process where feedback is key.

Deep and Melodic House music producer

I create infectious Hip-Hop & R&B vocal melodies, hooks, and full song concepts (“voice beats”) that turn a beat idea into a ready-to-produce song. Producers receive my vocal concept and can turn it into a full original track.

Emmy-nominated artist and producer behind records for Super Bowl LIV, MSC Cruises, Les Anges (France), the United Nations, and major tourism campaigns. I specialize in high-level vocal production, harmony architecture, melody coaching, and shaping undeniable, radio-ready records.

I am an underground artist looking to grow and expand my brand. I’m specifically trying to find my people and where I fit in the industry.
