About

I’m a composer and sound designer with 10+ years of experience creating original music and custom sound design for film, advertising, motion graphics, and media productions. I compose across cinematic orchestral, electronic, pop, and ambient styles, delivering audio that’s tightly synchronized to animation, transitions, and on-screen action.

I also handle sound post workflows end-to-end—from creative direction and music editing to mixing and mastering with broadcast and online loudness standards. Whether I’m working on short-form campaigns or longer productions, I collaborate with clients remotely, incorporate feedback efficiently, and deliver polished final mixes for games and media titles.
