    I can solve your problems.

    United States - Last active: 05/29/2014 - Tests: 1

    Sometimes I code. Sometimes I consult. Sometimes I test things. Ultimately, I solve problems for businesses. Over the span of 15+ years, I've been successful helping many companies around the world with whatever their problem might be. Name a technology and there is a good possibility I've used it and applied it where appropriate. I don't fit the standard mould of being a <tech> guy. This breadth of skills is powerful for the right customer who understands the capabilities I can offer. I assume since you are looking for help on Odesk that you are looking for affordability and flexibility. I can offer both.
