Small, sharp software,
crafted end to end.

Three things I'm shipping.

Different stacks, same obsession: tools that do one thing beautifully — from native desktop to the browser.

Tracé

Live

GPS tracks, rendered as art.

Upload a ride, run, or hike and watch the line you traced become a print-ready poster — designed free in the browser, paid only when you love it. Renders in a Rust→WASM engine, runs entirely client-side.

Seelie

Open source

A desktop pet that lives in your editor.

A native companion that reacts to your AI coding tools — Claude Code, Codex, OpenCode. Under 10 MB of RAM, a sprite-pack engine for custom characters, Lottie animations, and hot-swappable multi-provider TTS.

  • Qt6
  • Lottie
  • Cross-platform

Globe

Open source

A live Earth on your desktop.

A tiny desktop widget that spins the real Earth — accurate day/night terminator, city lights on the dark side, a flat-map mode, and a home marker that finds you. A growing solar-system view is on the way.

End to end

Design, build, and ship — no hand-offs, no committee.

Small & sharp

Tools that do one thing exceptionally well.
