A programming junkie and computer history aficionado, Tomer's been an avid software professional for almost two decades, during which he's built any number of (predominantly back-end) systems, cofounded two major Israeli user groups (Java.IL and Underscore), organized an annual Scala conference (Scalapeño) and is a recurring speaker at software conferences. Plying his trade as a gun-for-hire at Substrate, he secretly still hopes to realize his childhood dream of becoming a lion tamer.
