A software & making workshop, run by one person after work.

A small workshop, a few crafts.

Everything here starts with something I wanted but couldn't find — so I built it myself. Some of it turns into an app, some into a printed part, some into a script that quietly runs at night.

Android apps

Small, focused apps in Kotlin and Compose, built to solve one everyday problem properly.

3D printing

Functional parts drawn in Fusion 360 and printed to actually get used, not to sit on a shelf.

Automation & infrastructure

Backups, sync jobs and small services that run in the background so I don't have to think about them.

Desktop tools

Python utilities for comparing files, searching media libraries and automating slow manual work.

Some of what's running.

No names and no download links — these are private tools, built for one household and one machine. This is just what they do.

Also on Android

Also on the desktop

Most of these took a few evenings. None of them are products — they exist because the alternative was doing the same thing by hand every week. If one of them sounds like something you need, or you're curious how it was put together, ask me about it.
