Circles are cool.

Circles are cool.

A programmer in San Francisco.

I'm Sergio Villarreal. Mexican, transplanted to SF, used to work for a startup (Slide), which got acquired by Google, where I stayed for 4 years (mostly at YouTube). Now I'm working towards a better way to conduct biotech research with Emerald.

I like to program, take photos, bike and write. I accumulate hobbies and obsessions faster than I change underpants. This site is meant to document them.

The hobbies and obsessions, not the underpants.

Because that would be weird.
