Shipping QR self-ordering for restaurants — solo, with AI

What I shipped

Diners scan a per-table QR, browse the menu without logging in, order, pay, and the order lands on the kitchen display and auto-prints a station ticket.

The hard parts

• Pay-first to stop walk-aways. The first version trusted diners to pay; I closed that loophole so an order only enters the kitchen after payment.
• Session isolation per table. A new diner at the same table should never see the previous party's orders. I added a per-table session boundary with a 24h fallback.

Working with AI

I drove the whole thing with AI coding agents — planning each change, reviewing the diffs, and shipping daily. The leverage is real: one person can now build and operate a system that used to need a team.
