    Analog and Digital Designer - Over 20 yrs. Exp.

    United States - Last active: 2 months ago - Tests: 2 - Portfolio: 1

    Experience in small signal analog design, sensor interfacing, signal conditioning, sensor applications, data capture and analysis, digital design, microprocessors and small FPGA based systems. I have over 20 years experience developing ideas and bringing them through the design process to a finished product. I develop entire systems, including power, mechanical, optical, and software aspects. I excel in small, innovative designs using new technology. I design for durability and dependability coming from a background of experience in designing for harsh environments, high volume production lines, medical, and space applications. I have design experience in serial communications, optical systems, rf communications, programming, DSP hardware and software design, PC board design and technical writing. I offer my services to take your idea and bring it all the way to production, or to fill any need in the process. I am also available for consulting, helping you to refine your ideas into something that is both manufacturable and functional.

    Jason M.

    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.
