John Berryman’s first career was as an aerospace engineer, but after several years in aerospace, he found that he most loved his job when programming or when working on a good math problem. Eventually, John cut out the aircraft and satellites and started working full-time with software development, infrastructure architecture, and search technology. These days, John works at Eventbrite, helping to build out event discovery, search, and recommendations using Elasticsearch.
