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 day job is with UpCloud. 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.
