Libraries & developer tooling
A published library and the developer-facing tools I build for my own daily use.
AxisDB ↗
A tiny embedded document database for Python, addressing JSON documents by N-dimensional coordinate keys. MIT licensed, so it drops into commercial code; published to PyPI: pip install axisdb.
Locus
A native Windows task board with built-in focus tracking. It fills itself from an active Claude Code session.
BuildPilot
A flight deck for the build scripts you run every day on Windows: it starts several at once, shows each one's state and live output, then stops them cleanly. It runs your scripts; it never becomes the build system.
ScreenState
Window layout profiles for Windows. Sign in and your desktop arranges itself, every window back on the display it belongs on.
Visitron
Page loads for every site and downloads for every release, side by side in one Windows window, with a daily history to read them over time.
CommandFixer
PowerShell command autocorrect for mistyped commands.
Coin Analysis
A numismatic coin analyser using a hybrid of OCR and a scikit-learn classifier.
