I have been programming since the early 1980s. I have worked for many years for the emergency response division of NOAA (part of the U.S. Department of Commerce) on emergency response software for hazardous chemical and oil spills. In the past I worked for a few different game companies, including Sierra Online (later Sierra Entertainment). I have worked on a few medical devices. I worked for a year at Amazon. I have also done a lot of programming projects on the side, including a number of games for iOS and Android, and more recently some games and SaaS projects for the web.
