William M. Goodwin

Senior Software Developer

I help my clients solve complex scientific/engineering/mathematical problems using state of the art tools and techniques, underpinned by solid real-world on the job experience.

A thoroughgoing background in the nuts and bolts of computer software development supports my academic and hands-on mathematical knowledge. I am fluent in a variety of computer programming languages, from low level assembly language to C++ or Visual Basic. Large scale systems analysis and design is another of my strengths, bolstered by involvement in a number of major NASA software development projects. At the other end of the spectrum, I have successfully developed I/O device drivers and other kernel level applications under different operating systems. Through ownership and operation of my own company, I have expanded my knowledge and abilities in the business realm, as well.
