Things I build myself.
Products and open source I run alongside client work. Pilot Shell is the harness I use on every engagement.
Pilot Shell
How real engineers run Claude Code and Codex
- 2k+ GitHub stars
- macOS / Linux / WSL2
- Claude Code & Codex
Claude Code and Codex write code fast. Pilot Shell is the harness around them that makes the output production-grade: quality gates on every layer, memory that survives sessions and travels through the repo, code intelligence in the toolchain, and runtime proof before anything counts as done.
Bahnsparer
Fares, reliability and live journeys for German rail
- iOS, Android & desktop
- Free, no account
- Data stays on device
Bahnsparer compares fares, travel time and historical reliability across operators, then watches a fixed day or a range of up to 14 days for a better price. After booking, it follows the trip live, records the arrival and prepares the facts for a possible passenger-rights claim. Every request runs on your device, and there is no account.
DIY-Thermocam
Open-source thermal imaging for everyone

- C/C++ · FLIR Lepton
A do-it-yourself thermal imager around the FLIR Lepton sensor: firmware, PCB, enclosure and desktop suite, all public and buildable at home with standard tools. It began as my bachelor thesis and is now used by makers, schools and companies.
