Home-search agent
Scores rental listings on commute and affordability, then drafts and sends agency enquiries. Learns my taste from thumbs, notes and my edits to its drafts, distilled into rules applied deterministically. Booked 11 viewings into one afternoon; it found the flat.
Ward-round simulator
An LLM-driven trainer that generates patients, drives interruptions against a clock and marks free-text clinical reasoning against rubrics. Opens each session on the weakest material and exports a cumulative gap profile. Explicit about what the mark does not certify.
French-for-finance tutor
Reading, writing, vocabulary and spoken roleplay over SM-2 spaced repetition, with generated exercises, neural speech synthesis and Whisper recognition. Model calls route down a provider chain, so one tier's rate cap never stops a lesson.
Grocery-first recipe app
Starts from what is in the pantry, not from a recipe: a scoring engine ranks dishes by essential-ingredient coverage over an ingredient hierarchy, computes the shopping list for the gap, and an LLM decides what to cook. Bilingual EN/CN. Drove a 200% increase in home-cooked meals over eating out.
Social media OS
A learning feed over arXiv, Hacker News, GitHub, Reddit, RSS and X that ranks on what I actually open, plus a publishing dispatcher for LinkedIn and X behind brand-fit and IP guards — with a durable click marker so a timed-out publish can never double-post.
NHS record-fragmentation map
Mapped the electronic-record vendor across 2,536 NHS hospital sites with per-site confidence and sources, then tested 12 adjacency clusters for whether neighbouring trusts actually share a patient record. Mostly they do not.
