About me

I'm currently working as a freelance software developer. I've been a professional programmer for the last 20+ years working on everything from industrial automation and SCADA systems to embedded systems and educational robotics. I'm a huge opens source fan and have contributed to 100s of open source projects over the last 10+ years.

A big part of the last 10 years has been LEGO robotics. I have done everything from coaching and judging FIRST LEGO League teams to reverse engineering the latest LEGO robotics platforms to build complete 3rd-party open-source alternatives (LEGO actually encourages this, in case you might be questioning the ethics of reverse engineering).

Major projects

Here are some of the projects where I have spent the most time contributing and maintaining and are actually used by 1000s of people.

  • Pybricks: MicroPython for LEGO Powered Up smart hubs
  • Bleak: A cross-platform Bluetooth Low Energy Python package
  • ev3dev: A full Debian Linux distribution for LEGO MINDSTORMS EV3
  • KeeAgent: An SSH Agent plugin for the KeePass 2.x Password Safe

Notable contributions

Here are a few bigger projects I've contributed to that are fun to tell about.
