Founder and project leader

Before Zulip, Tim was a founder and CTO of Ksplice, which provided rebootless linux kernel updates (a feat many previously thought impossible) to over 100,000 production servers. He was also the youngest ever Architect at Oracle, one of the most senior engineers at Dropbox and has been active in the open source community for over a decade. Tim has three degrees from MIT, and lives in San Francisco with his wife and daughter.
