Thuan L. Thai started computer programming 15 years ago but has never been tired with this hobby--one that he truly considers an art. He is currently a senior systems engineer at SAIC where he has led the architecture and development of several successful distributed and COM-based imaging systems. He also teaches Win32, MFC, and COM programming courses for Learning Tree International. Prior to all this, Thuan worked for AMS where he developed multi-tiered, object frameworks using C++ and RPC. He received his bachelor of science in computer science from the University of Virginia. When not developing software, Thuan enjoys strumming his six strings and writing songs every now and then. He often plays 9-ball with the same buddies with whom he has played the game for over eight years. Thuan hopes to play more tennis, the only sport that he has ever played for more than eight hours in a single day.
