Things I’ve built that got far enough to have a name. The ones that didn’t work are usually the better read.
Photos in, eBay listing out. An AI pipeline with live comps, taxonomy mapping and model fallbacks, plus free reseller tools and price guides. Rebuilt from scratch in 2026 with an eval harness behind it.
A buyer's guide to secondhand. 39 shops, one per category, each with fact-checked models, used-price ranges from dated eBay snapshots, and picks over live listings.
How I build. First: ten scheduled Claude Code agents that took ideas to live sites with no one at the keyboard, for three months. Now: a tighter loop that takes one job from ticket to a verified deploy.
A portfolio that reacts to its own conditions. It notices when you go offline, and there's more here than the nav admits.
A map of every stop on a neighborhood garage sale day, filled by an AI pipeline that reads the organizer's messy list. Built in three days, never shipped, now live as a labeled demo on a sanitized dataset.
Pick a decade, watch a period terminal fall through a wormhole, and land on what an old purchase is worth today. A design piece built by the factory's agents, with no ads, no tracking and no point except to be shared.
One short form, three quotes from local rental companies, no spam. The vendor emails, their replies and the comparison all run through one inbox. The most engineered thing in the factory. It never launched; it's live now as a demo that can't reach a real person.
