Software Developer in Redding, CA, United States

A C++-based video editing application for desktop Windows, using the wxWidgets library for the HMI and the FFmpeg library for video rendering. After starting this as a personal project, it became a full-time job as a startup entrepreneur. At its inception in 2004, there were not many video editing applications, and most of them were quite slow.

The idea was to develop a very fast application with a very fast HMI, written in templatized C++, using an optimized widget drawing system designed for video editing and written entirely from scratch. I collaborated on this project with my father, also a software engineer, and he wrote the audio rendering part of the project.

I led this project to the first fully functional version, which was four years after the project was initiated. While serving as the project manager, architect, designer, and developer, I wrote nearly 80,000 lines of code. For urgent personal reasons, I stopped working on the application just before the beginning of the commercialization, but it is fully working. You can take a look at the HMI on the project website.

RCCS is a railway control center application, running on Windows, for supervision, control, and scheduling of high-speed trains between the Channel Tunnel and London. It is a critical environment because it's used to manage train routes, schedules, positions, and status. There were unresolved bugs in the software for many years, and system (not train) crashes sometimes led to huge delays on the highly frequented train line because the management of the whole train schedule depended on this software. Delays on this line were very expensive!

My role was to find and solve the very hard-to-find bugs, using a lot of inputs from circumstances, a memory dump, and a stack dump. Because I was able to debug the assembler code directly in a binary library (ILOG Server) that this software was depending on, I found the origin of the bugs and proposed a correction to fix them. After the corrections were applied, the software was very stable and there were no more delays due to the software.

A website for a non-profit organization that depends solely on gifts from people for its economical model. One of my main contributions was the development of an easy-to-use gift page based on Django-Python, CSS, HTML, and JavaScript. I made it very easy for people to contribute to the charity by entering their information and paying in a variety of easy ways. Contributions increased by 60% in the year that the page was deployed.
