About Jacob Stein

Experienced software engineer that specializes in high throughput, distributed systems. I’ve worked as an engineer for the past decade, on services that range from a large scale distributed key-value store serving close to 100 billion QPS to a distributed query engine that analyzes petabyte scale data. I’ve led multiple cross-functional projects to successful releases, designing, building and maintaining systems of scale.
