About

Business student at UC Berkeley. I learn by building software, marketplaces and games. Right now that’s alai, a voice-first AI tutor for STEM homework: students work by hand on an iPad, and when they pause after a wrong step, alai underlines it and nudges them out loud. On the side: Rally, table tennis with your phone as the paddle, and PigeonBox, an AI inbox that runs on your own computer.
