Expert multi-domain, full-stack developer

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.

This system links potential dog adopters to nearby dog rescue centers.

Rescue centers can upload images of available dogs and set basic iinfo about the dog such as breed, age, and gender.

Visitors can view the adoptable dogs from nearby rescue centers on a large-format carousel display, and if they find one can then reach out to the particular rescue center.

The system also periodically displays sponsor messages from dog-loving patrons.

iPhone + BLE sensor collects data samples.  Data is stored and analyzed on web server. 

I developed the entire prototype system,. This then became a team project once the prototype project was approved. I then concentrated on the iPhone portion, which involved BLE, a somewhat fancy UI, charts, database, and AJAX.
Smartphone Medical Diagnostics App
I developed the TenGun Point Cloud Pre/Post Processing app.  This is used to create particle data for SPH, DEM, and other types of engineering analysis apps, and then to view the results of those analyses.

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...
