I'm a professional software developer with 15+ years of experience. In my spare time I build free and open-source software, mostly tools I need myself, because none of the existing options worked the way I wanted. Everything I publish is free to use, and the source is public.

Projects

• Party Sync: an Android app that backs up your phone to a copyparty server you run yourself. There's no cloud, no account, and no Google services. My family and I rely on it to back up our phones.

More projects are on my GitHub.

What donations fund

Donations pay for the time I spend fixing bugs, adding features, and maintaining these projects so they keep working.

How I work

I use AI coding tools, mainly Claude Code, to build faster. I review and test everything that ships, and I'm responsible for every bug.

Bug reports and ideas are just as welcome as donations. Open an issue on the project's GitHub repository.
