I've been working, in detail, with computers for over 6 years.  I've done a little of everything: hardware troubleshooting, maintenance (Desktops, Laptops, & Sun Pizza boxes), programming (C++, dBase IV, Visual dBase, Visual Basic, Access, HTML, SunOS & Solaris Shell Scripting), Network SysAd (WinNT, SunOS, & Solaris), and basic graphics development.
On the side I've done contract work for Andersen Consulting.
With my AF career, I have worked with McDonald Douglas, Lockheed Martin, SAIC, Sterling Software, PRC, Assurance Technology, and BTG Systems
I am currently an instructor at a premier Air Force SuperUser/SysAd course.  Some of the extra stuff I do at work include Computer Security and Y2K.
