About

One developer, directly.

I'm Leon. I like building things that are actually useful.

I work independently from Germany on developer tools, Windows software, web platforms and infrastructure. Some of it is my own, some of it is built for clients — the projects on this site are what I've built and what I'm building right now.

LSP Virtual Services is the business behind it. There's no team and no pretending otherwise: one developer, working directly with the people I build for.
