    Expert Developer, Thought Leader

    United States - Last active: 09/18/2014 - Tests: 7 - Portfolio: 5

    I have been developing cutting edge software for over twenty years. My experience has been centered around ultra high performance embedded systems as well as modern web design and programming. I have been intimately involved in every aspect of the development lifecycle, including: brainstorming, requirements capture, resource management, graphic design, programming, testing, deployment, even sales and marketing. All of my projects are extremely thorough. I am more driven by the quality of my work than I am by the hours I will bill. I am also an entrepreneur and have spent plenty of time on oDesk on the other side of the fence, so I understand exactly what employers are looking for. That is why I am confident I can provide unprecedented value.
