I’m Sidney San Martín (a.k.a. s4y), a computer programmer and performer based in Brooklyn, NY.

I work on tools for performance, live music visuals, immersive art installations, 3D virtual spaces, systems programming, electronics, and almost everything else that involves a computer. I’m looking for creative collaboration and (some) contract work.

In the past, I've done full time software engineering at OkCupid, Keybase, and on Chrome for Mac at Google.
