I’m currently an Entrepreneur-in-Residence at Benchmark Capital Partners, in San Francisco.
These days, I’m currently most interested in machine learning, privacy, distributed systems and remote collaboration/telepresence. I often write about technology and sometimes invest in great teams. Drop me a line if you want to chat about anything tech!
Previously, I was a Director of Engineering at Twitter and Engineering Site lead for Twitter‘s NYC office. There, I managed a number of consumer engineering projects, worked on improving remote collaboration (e.g. by fixing videoconferencing), and even helped to fix a kernel bug! Previously, I was founder & CEO of Mitro (which exited to Twitter). I worked at Google from 2002-2009, where I designed and implemented some of the core systems infrastructure as well as parts of the ads system.
In 2014, I discovered that NYC’s Taxi and Limousine Commission released improperly anonymized taxi logs.
I’m an active angel investor. Some of my investments include Wish, Heroku (acquired by Salesforce), 280 North (acquired by Motorola), Octopart (acquired by Altium), SigOpt, and Seed&Spark. I’m also an advisor and Venture Partner at Hoxton Ventures, a London-based euro-centric investment fund.
