Currently working on Axiom, the best way to build a decentralized application. See https://axiom.org for details.
Previously, the founder of Parse (YC S2011), the simplest way to build a mobile app. We were acquired by Facebook in 2013 and had a few exciting years there.
Unfortunately, we shut down the hosted Parse service in January 2017. Fortunately, a lot of the Parse magic lives on as open source:
Before Parse, I founded Gamador (YC W2010). Millions of people have played Gamador's casual games.
Before that, I was a software engineer at Google working on search algorithms.
Before that, I was in grad school at Berkeley bouncing around between computational biology and AI.
