I’m Giancarlo Castro — a music producer, mixing engineer, podcast editor, and sound designer with over a decade of professional experience.
I graduated from Berklee College of Music, and since then I’ve mixed and mastered full albums, produced daily podcast episodes for global brands like The Economist and TurboTax, and designed original sound effects and music for games and interactive media.
My track “Closer” was featured in Riot Games’ Wild Rift Horizon Cup, reaching over 12,000 streams on Spotify.
What sets me apart: I don’t just make things sound good — I build efficient systems around the work. I’ve managed high-volume audio pipelines for global publishers and brands, and across my freelance career I’ve built lasting client relationships through clear communication and a commitment to getting the details right.
Whether you need a polished mix, a clean podcast edit, or immersive sound design, I bring both the technical depth and the discipline to deliver on time.
