About

I'm a product manager at Google — previously PM at Firebase and Lyft, and co-founder of Kicksend (YC S11). I'm also an angel investor and a venture partner at Pioneer Fund.

Before product I shipped code — Ruby, Rails, iOS, Mac — and wrote two books about it for Manning: iOS 7 in Action and MacRuby in Action. Along the way I picked up four patents in assistant UX and mobile observability.

Off hours I design practical 3D prints, race on iRacing, and build small products around the things I care about — which is how most of the projects below happened.
