My primary area of interest is Linux embedded development.
See the following page for origins of my Linux background:
- Quester Tangent, Sr Embedded Developer, Apr 2012-2017
- Develop embedded Linux distribution to run on
the Freescale i.MX53 ARM as part of a train control and monitoring system.
- Develop/integrate low level Linux device drivers for PWM, Wifi, GPIO, touchscreen, etc.
- Develop applications to collect, concentrate and
relay data collected from train devices using C/C++.
- Embedded device user interface development using websockets.
- PDQ Interfaces, Computer Consultant, Oct 2003-Present
Provide computer consulting and research services.
- Itron Inc:
Project to develop a wireless embedded Linux device (the Itron CCU) for use by utility providers of power, gas and water.
The work involved developing a SSL-web standalone application using C and Tcl to capture
meter readings, in a store and forward fashion. High reliability requirements included an MTBF of 20 years.
The device application and OS were managed via rpm, including support for automatic download and (re)install of the
Linux OS via a firmware bootstrap application.

Covigo (a Silicon Valley firm) contracted enhancing
Browsex (my open source Web Browser)
to support record and parametrized-playback
of web content.
Web software support was required for client and server modes,
on both Windows and Unix.
The target market was cellular and wireless devices.
