Less friction. More building.
Engineering manager · Developer tools maker · Ansbach, Germany
I lead Platform Engineering at Tradebyte, where we're building an Internal Developer Platform to help engineering teams ship software with less friction.
Outside work, I build open-source tools with a shared shape: local-first, one binary, plain files you can read in Git, and usable by people and AI agents alike. I like small, focused utilities. This occasionally escalates into building a shell.
| If you want to… | Take a look at… |
|---|---|
| Keep your todos in your repo | tdx — a terminal todo manager with Vim-style navigation. Your tasks stay in plain Markdown. |
| Launch apps with a key sequence | Keywink — a native macOS launcher. Type a few letters; the on-screen guide shows the way. Config stays in JSON. |
| Remember why you decided something | vrdx — engineering decision records in Markdown, with a local dashboard and structured context for agents. |
| Turn architecture into diagrams | Sceno — describe it in KDL, preview locally, export SVG, PDF and slides. Agents can iterate until it validates. |
| Give an agent credentials without handing over the vault | Latchrun — scoped sessions from 1Password or pass, approved commands only, replay-safe. |
| Ship a Python CLI as one binary | Kipferl — write Python-style scripts, get a fast standalone executable. |
| Explore a different kind of shell | Quirl — familiar Bash commands, typed data pipelines, and Lua extensions. |
- speed-comparison — the same computation across dozens of languages. Eight years old and still surprising me. What a benchmark measures.
- Kindred — a family-history graph built from Markdown notes. No account, no subscription, just your family's stories.
- Overhead Overdrive — a 3D overhead-projector racing game set in my old school. The story behind it.
- Spokn — a macOS text-to-speech panel with karaoke-style highlighting. Swift and AppKit, no cloud.
- dotfiles, for the terminal-curious.
