I’m Sidney San Martín.

I write software and live in NYC. As of June 2016, I work on Chrome for Mac at Google!

I’ve dabbled in adding asynchronous programming to C++, putting a window manager in your browser, and putting live HTML in your terminal. I was in batch[2] of The Recurse Center.

My favorite programming concepts (for now) are coroutines, closures, and idempotence. I daydream about strong AI and making programming easier.

You can find me on GitHub, Twitter, Keybase, and Stack Overflow. You can email me at
