I co-founded Zenysis and lead its engineering team. Before that I worked at Google, mostly on travel search (via acquisition of Room 77).
A while ago I created Asterank, which was acquired by Planetary Resources. Afterwards I began consulting via Alioth with a focus on data visualization, working with NASA, SETI, and various private companies.
