I lead engineering at Mashgin, where we build AI-powered self-checkout for retail and stadiums. Before that I ran engineering at Doxel, bringing computer vision to construction sites.

Earlier in my career: Google (tech lead / manager on the Google+ Stream backend, also worked on Search), Twitter (Twitter Ads; founded the company’s internal engineering-leadership program, TWIG), TellApart (software architect on the ad-bidding stack).

The through-line is high-performance systems and the teams that own them — the rare combination of caring about both the machine and the people running it. I started writing the Open Leadership & Management Cookbook to capture some of what I’d learned about the second half.

UC Berkeley, 2000–2002. Now in Redwood City, California.

Outside work

I co-organize a Bay Area fusion-dance community, climb, ski, mountain bike, and travel when I can. I’m on the Boosters Board for WHS Robotics Team 100Woodside High School’s FIRST Robotics team, “The Wildhats,” founded 1995, first FRC team on the West Coast — and spend a chunk of time on civic-accountability projects.
