The résumé. Every line links to the thing itself.
- A small language model, by hand, in two days — tokenizer, cache, pretraining, chat. It hedges where I hedge.
niels-gpt, working notes
- A reading system where a highlight is a codepoint range into canonical text. When client and server disagree, it refuses to highlight.
Nexus, source
- LLM agents wrapped around a deterministic scheduler. They may explain the plan; they may not touch it.
Factory Simulator, working notes
- A reader that ingests messy PDFs and answers from the text it was given, not the text it wished for.
Fractal Chat, working notes
- A real-time multiplayer Go board, built for a friend, who thanked me by winning on it.

- A map of a music model's range: clips clustered by sound, regeneration steered toward the region you point at.
Suno Session Lab, working notes
- Two plain-English walkthroughs of backpropagation, written for the person I was in October.

budget-app, domain layer
- This site: typed data for a CMS, evidence links checked at build, two client components. The colophon confesses.
