    Software Developer C#/F#/Javascript & SQL Server DBA

    United States - Last active: 1 day ago - Tests: 2 - Portfolio: 2

    Over the past 10 years I've developed software both professionally, and as a hobby. I enjoy working on more than just my daily grind, so I've come here for a little something extra. Do you have an interesting project? Read on, I may have the skills you need. Let's talk desktop/back-end development: C#, Ruby, Go, C, Objective-C, Powerbuilder, SQL (ANSI/MSSQL), Perl. Those aren't languages I've just spent a few hours on; I've shipped products or currently maintain projects in those languages. How about web development? I love writing responsive, cross-browser/cross-platform sites that work as well on the desktop as they do on your phone or tablet. It's a great challenge to stay ahead of the curve.
