I have been a professional developer since 1996. My experience comes from many different industries; Data Mining Software, Consulting, E-Commerce, Wholesale Operations, Clinical Software, Insurance, Energy.

I started programming in the military, trying to find better ways to analyze database data, eventually automating my entire job. Later, in college, I automated my way out of another job. This gave me the great idea to switch majors to the only thing that seemed natural…Programming!
