Josh spent his college years programming robots to play soccer in the RoboCup SPL league. There, he learned to love when very complicated computer systems break. This passion for broken computers led him to take an SRE job at Google working on source control systems. Six months ago he moved to Cockroach Labs to work on a DBaaS. Josh enjoyed Borg while at Google and has since spent many long hours puzzling over the strange land of Kubernetes. Josh can often be found roaming the Cockroach Labs NYC office yelling about things like strange node pool API semantics much to the confusion of his coworkers who don’t work on Kubernetes.
