...Derek’s skills as a software developer proved themselves valuable to our team time and again. I’ve lost track of the number of times over the years Derek has solved seemingly impossible problems under ‘pressure cooker’ deadlines.”

(Letter of Recommendation, late 2004)
Derek is a strong performer, extremely dedicated and makes a valuable contribution to the team. He shows leadership tendencies, and takes the initiative to keep the team on task. [...] Even under somewhat difficult circumstances, Derek has pulled team members together and accomplished the required tasks. [...] He has continually helped other developers in other departments resolve development issues.”

Example Projects

Hydrogen Fuel Cell Charger (Firmware)

I worked on the firmware team for a consumer fuel cell device. Features included hydrogen fuel management, temperature measurement, event logging, and safety modes. My code included HAL drivers, Mfi and iAP protocols, and a flash partition manager.

NOAA Joint Dispersion Modeling System


I developed software that offers an advanced, interactive web interface for running simulations on two atmospheric modeling systems. This was a joint project of NOAA's Air Resources Laboratory and NOAA's Office of Response and Restoration, and I worked closely with team members from both offices. This work included access to restricted computing resources and required an FBI background check.

Aircraft Maintenance Tool (for Panasonic Avionics)

I led a senior 'agile' software development team to develop an engineering maintenance application for PAC's latest IFE products. It processes engineering data from the aircraft (transmitted via satellite) and displays it in real time on a web-based interface. Multiple protocols, data formats, and back-end architectures were involved.

On Demand TV (Launched in Japan, Mar. 2005)


From the Article: “ODTV, short for On Demand TV, means that you can watch what you want, when you want to and on what you want.” I was on the team that developed the client side of this service (the embedded Linux user interface for the set top box). This was a major service release in Japan.

Targa 3D Game Engine (Hobby project)

I developed an OpenGL-based BSP game engine in C. I integrated 3rd-party C, C++, and Python libraries into a modular architecture that included scriptable entity behavior and a widget-based GUI system.

SNMP Proxy for High Bandwidth Microwave Radio Transmitters

I wrote Linux server software to integrate 2.4GHz DS3 Radio Hops into an HP OpenView-based Network Operations Center. The stateful SNMP proxy translated packets to PCOM's proprietary serial protocol.
