I started building my BeatStars catalog to showcase my work as a music producer and composer across multiple genres, including hip-hop, trap, phonk, cinematic, and electronic music. This portfolio reflects my approach to composition, sound design, arrangement, mixing, and mastering.
BeatStars Portfolio:
One of my beats was licensed and used by U.S. rapper Caskey on the track “Hex My Enemies”, demonstrating my ability to create commercially viable productions for professional artists and the international music market.
I’ve always dreamed of scoring and recording music for a film. So I grabbed the first video I could find, generated by Grok Imagine and created by Alex Utopia from X. Full scoring with sound effects and sound production, including mixing and mastering. That one-minute story was completed with sound in just two days. One day for sound design, the next for mixing and mastering.
