I am a senior programming consultant with many years of experience in the industry. I also served as an Ambassador in the Greater Dallas chamber of commerce and was awarded two Ambassador of the quarter awards and presented with an Ambassador of the year award, for 2006, in January of 2007. My experiences range from DOD classified work, with the U.S. Air force, to building high stakes gaming apps and working on military flight crew training simulators. I am flexible with my working hours and am very happy to work with any existing free lancers who may already be working on a project. Close communication with team members is one of my specialties. I am primarily looking for either short, or long, term projects as I have the experience, and ability, to handle either very well. This would include, in some cases, those with rather short deadlines. I am pretty good at making deadlines, even some that might seem unreasonable. I look forward to discussing your project needs with you!

Low level programmer, love to make things run fast! Have prior work experience on fluid dynamics simulations, embedded systems, and cryptography - if it doesn't need to be efficiently done I get bored!
