I am a highly experienced C/C++ programmer specialized in 3d graphics, games, and educational software for more than 15 years. I currently focus on apps and games for mobile devices and can deliver cross-platform solutions for Android, iOS, Windows, OSX, and even Tizen. I am an American living abroad in Lisbon, Portugal where I was formerly Lead Programmer for Biodroid Entertainment heading up the console division, having worked on titles for Wii and PlayStation3. My online published titles include "vSide" and the Jason Project.
