I am a hands-on engineering/operations leader who builds meaningful and interesting Internet software. I have experience with distributed systems of thousands of servers, or a single site. I'm working on being a full-stack engineer by writing code nearly every day. I write Python for fun. I've led core engineering and ops groups at Akamai, VMware, Ning, and now Stanford. Although I've managed 140 engineers across three locations, I prefer small teams who move fast. Last summer I lead a team that built and launched an open-source MOOC platform in eleven weeks. One of my blog posts hit the top spot of Hacker News. BS Computer Science, Stanford 1993.
