    website mechanic

    United States - Tests: 1 - Portfolio: 6

    I can fix your website. I can fix you a website. No job too small. No problem is too complex. I'm an expert in what I do and I never take jobs that are beyond my limits. I always deliver what was promised and I despise second-rate quality. I believe that a list of tested skills is only one side of the coin. Reliability, good communication and ability to understand are as important as technical competence. I have a day job so I'm looking for assignments that I can do in the evenings instead of wasting my time playing battlefield for hours. :) Even though I registered 2 years ago I'm new to Elance so I added some samples to my portfolio from my previous projects.
