Peter is the co-founder of Cockroach Labs where he works on a bit of everything, from low level optimization of code to refining the overall design. He has worked on distributed systems for most of his career, designing and implementing the original Gmail backend search and storage system at Google and designing and implementing Colossus, the successor to Google's original distributed file system. In his university days he was one of the original authors of the GIMP and is still amazed when people tell him they use it frequently.
