Gil Zilberfeld has been in software since childhood, writing BASIC programs on his trusty Sinclair ZX81. With more than twenty years of developing commercial software, he has vast experience in software methodology and practices. Gil has been applying agile principles for product development more than a decade. From automated testing to exploratory testing, design practices to team collaboration, scrum to Kanban, traditional product management to lean startup – he’s done it all. He is still learning from his successes and failures. Gil speaks frequently in international conferences about unit testing, TDD, agile practices and product management. He is the author of "Everyday Unit Testing", blogs at http://www.gilzilberfeld.com, co-organizer of the Agile Practitioners conference and in his spare time he shoots zombies, for fun.
