Veteran, expert system developer in multiple domains including web apps, iOS and Android, embedded microprocessor systems, High-Performance Computing with NVidia GPUs (CUDA), graphics, database, and telcommunication systems. Large scale projects from concept to development to marketing no problem. Longtime U.S. expat in Japan, so bi-lingual in English & Japanese. I am fairly new to Freelancer (but not at development), so I only have a few Freelancer "references" and "credits" so far. Personal references and examples of various projects, both small and large, will gladly be provided upon request.

Hands down, amazing work. William is very knowledgable and professional, clearly experienced in the technical industry; I had a somewhat messy codebase, and through thorough documentation and communication, they were able to meet and exceed the expectations while being flexible in a very practical project-oriented mindset.

I am often conflicted with the use of superlatives when giving feedback reviews but in this instance I have to say that working with Bill was an absolute pleasure. Easy. Intelligent. Thinking and Doing above and beyond the call of duty, so to speak. Having been a Developer myself for a long time and now being an Agile Coach, I recognise when behaviours of a technical person are advancing a project forwards and Bill was always thinking of ways to move the project forwards. Would definitely work with him again

Our project was to re-write some ugly Fortran code from the 1970's into modern C++. Bill did a fantastic job translating the code and massivly improving the user interface. Bill was consistent in communication, even being 13 hours different. His dedication to our project was apparent. His high degree of experience shines thru his code. He's patient to explain aspects you don't understand. Would work with him again, absolutely, and would be our first choice for any software development.

The Software Bug Book: Thoughts on Software Quality

Developing, managing the development, and selling software applications require entirely different skills sets. For developers, this book explains how to detect and correct Memory Leaks, Resource Leaks, Deadlocks, Data Races, and other complex bugs. For non-tech people, this book introduces some jargon that you should be familiar with, introduces "bugs" in an easy-to-understand way, and gives insight into what to realistically expect from your developers. ...and more...
