Maurice Sharp is a 21-year veteran of mobile development at companies both large and small, ranging from Apple, Palm, and eBay to ShopWell and Couchsurfing. Maurice got his start as an intern developing the Newton ToolKit prototype, then as a Developer Technical Support (DTS) Engineer helping make the world safe and fun for Newton and Palm developers. After mastering the DTS side, he went back to coding, and he currently manages and does mobile development at Couchsurfing; runs his own consulting company, KLM Apps; and is ex officio technical advisor to some mobile-focused startups. When not living and breathing code, Maurice spends his time being a husband, and a father to a precocious 10-year-old girl-his two most important roles.
