Since moving to the Bay Area in 2001 I have been working at Pixar. Prior to that I lived in China and was the Chief Software Architect at AsiaInfo, the company that built China's internet. I studied computer science and worked in Texas for many years. feel free to drop me a line if you've got any feedback on stuff I've posted here:
