About the Author

Andy Bantly
Founder
United States United States
Working as a software developer since 1989. Started out with Basic, FORTRAN and JCL, moved into Visual Basic 1.0, C, then C++, and now I work mainly in C++ using MFC, Win32, and ATL/COM. I use Microsoft Products only because that is what gives me gainful employment. Through work, I have a lot of experience with HTML, JavaScript, XSL transformations, the XMLHTTP object, PHP 4.x, and simple COM object integrations.

I've worked for the University of Oklahoma in the school of meteorology (Go SOONERS!), consulting, and now as a Senior Software Engineer. These things keep my lights on and electricity going. My dream job is to own a bowling alley and rub elbows with pro-bowlers! I'm also an avid pedicab driver and have my own cab. I like the hustle of picking up people in downtown and biking them to their destination.
