    ★Web | Print Designer | MCSE Certified Computer Tech★

    United States - Last active: 03/31/2010 - Tests: 6

    All throughout my college career, I have honed my skills as a Web and Graphic Designer, as well as many others. I'm your stereotypical "get-it-done" computer geek, and my most valuable skill is my ability to diagnose and treat problems through research, either on the web or off of it. I am based in Virginia, but willing to do work anywhere. As I wrap up remaining General Education credits at my university, I hope that ODesk will allow me to market my skills to the people who need them most. My greatest proficiency is in design based applications such as the Adobe Creative Suite, but my knowledge of operating systems, networking, programming, computer troubleshooting and repair, and optimization is more than adequate.
