    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.

    Engineer

    United States - Last active: 10/31/2012 - Tests: 3 - Portfolio: 1

    Over the last 3 years I have developed a variety of hardware and software in C, C++, and C#. My core competency lies in design and debugging of small to mid size programs. I am seeking opportunities to build apps/programs from the ground up for you or your business. I have studied cutting edge technology with hardware as well as software. I have picked up my trade extremely fast. My portfolios below demonstrate my robotics work. I taught C++ and Java at a summer camp last year and it really pushed my skills and abilities! I am now much more confident in both languages. I can do iOS programming, but I don't have a mac at the moment. I've worn lots of hats in my day any other questions just ask.
