Things I've built

This site, self-hosted on a VPS.

A structured math database containing over a million problems with answers, solutions, and LaTeX statements, stored as gzipped JSONL shards.

A website for throwing an awards ceremony for your friend group, like "most likely to cancel plans" or "best group chat moment of the year," where everyone votes on their phone and the winners get revealed on a TV.

A Rust workspace that lets AI agents write music as a declarative score, render it offline to bit-for-bit deterministic audio, then "hear" the result through extracted numbers like loudness, pitch, onsets, and spectrograms so they can assert on what they made without a human ear or audio device in the loop (featured in "This Week in Rust" issues 660 and 661).

A pure-Rust GUI framework with web-grade looks, whose headless renderer is a deterministic pure function of tree, theme, and size, so people and AI coding agents can describe a UI in Rust or JSON, render it with no window, and pixel-check it in CI.

A science-popularization website where you upload any image, choose an environment, and watch its colors age across five centuries, quantified with the CIELAB ΔE metric and calibrated on real pigment-aging data.

A local-first macOS desktop app and a standalone pure-Rust terminal client that seat eight frontier models from eight providers in a moderated, streaming debate on any question and close it with a vote and a scored verdict, sharing one encrypted session store between the two surfaces.
