A UK aquarium's ticketing system rebuilt by a non-developer
Over four weeks the owner of a small UK aquarium used Claude Code to replace a closed ticketing system with online booking, a staff till and a self-service kiosk, backed by 374 tests. It is not live yet.

The full story
A small UK aquarium run as a community interest company was locked into a supplier's ticketing system for its kiosk, booking site and gate. Small changes cost over £500 a day, licences came on top, and there were faults: a card charged with no ticket printed, an hour-out bug at the clock change, tickets reused at the gate and card sales re-keyed by hand.
Over about four weeks the owner, who isn't a developer, built a replacement with Claude Code. They wrote a specification of about 20 decisions (prices, refunds, opening hours, what happens when a payment drops out halfway) and built it in tested stages. It covers a three-step online booking site with payment through Square's hosted checkout, a staff till and a self-service kiosk, with the entry gate to follow, and has 374 automated tests.
It sits on a password-locked test site and is not live yet; the post asks experienced developers what to check before switching it on.
