I have nearly forty years of programming experience, thirty of it working full time. I have code running on billions of devices, on all continents, on all oceans, in orbit, and on Mars.

My primary job is with Radicle, the distributed git hosting system. On the side I give a course in the basics of the Rust language, invoiced via my own company, Lars Wirzenius Consulting Ltd.

I am passionate about software freedom. I sometimes give a free, condensed version of Rust course for free and open source software developers.
