Before I moved to the dark-side of VC, I built + ran Uber's Public Policy Product & Technology division, which was a crazy and eye-opening experience going from ~1000 worldwide to 6000+ people when I left.
I am also one of the two founders of WP Engine (http://wpengine.com).
A long time ago I helped build the BBC News Website as a software engineer, back when Objective C was a server-side language :). I went on to design and run the BBC's developer platform and later I was Director of Engineering for MySpace's Developer Platform - back when MySpace was a thing, I promise.
