I was Software Engineer at Armadillo Software Corporation in Austin, Texas between getting my master's and PhD degrees. I was one perhaps the fourth full-time engineer hired. When I left, my boss told me I was crazy - they had just landed a contract with Dell and "we're all going to be rich." Two years later there was no Dell contract and only one engineer left.
I have also developed software for Federal Express in Colorado Springs, Micro Insurance Software in Denver, and smaller businesses in Houston and Austin.
