John Berryman started out in the field of Aerospace Engineering but soon found that he was more interested in math and software than in satellites and aircraft. He soon made the leap into software development specializing in search and recommendation technologies. John is now a Senior Software Engineer at Eventbrite, where he is helping build Eventbrite's event discovery platform. He also recently coauthored a tech book, Relevant Search, published by Manning. The proceeds from the book have mostly paid for the coffee consumed while writing it.
