I started contracting software development in 2002. Mainly I develop embedded systems code (in C) and simulation systems (in C++). I've been coding for the Folding@home project since 2007 and have been working on an Open-Source 3 axis CNC simulator called CAMotics since 2011.

I live in Petaluma, CA. If you're in the area, send me an email. I'm always up for a coffee or a beer and interesting conversation.

  13. Ask HN: Are you using Docker as a build environment vs. deployment system and how?

    I've been using Docker mainly to setup build environments to target and test bulids for multiple Linux distros and even for cross-compiling for Windows and macOS. I believe that the biggest problem with software…
