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.

  1. Ask HN: My Open-Source project is on eBay. What should I do?

    I just find out that my GPL'ed CNC software, CAMotics is being sold on EBay. The seller clearly made modifications and I don't see any way to access the modified source. Isn't this a license violation? Has anyone else…

  12. Ask HN: Have you created a programming language and why?

    Excluding school projects and toy languages, who here has created a programming language and why? I'll go first. 13 years ago I created a specialized language for processing XML data. XmlPl marries the syntax of C, XML…
