I'm Jonathan, a .NET and Webdeveloper by day and night.

I enjoy cycling, games, music, food and a lot more. I'm interested in mental health, sustainability, right-to-repair, privacy and more. You can find out more about me or this site, check out my blog, download my CV, or look at some projects I did.
