The challenge

A working-class New York-style pizzeria in Florida that takes orders live at the bar wanted a digital surface that matched their operation — not an off-the-shelf cart bolted to a marketing page. The real ask was printer-to-kitchen reliability: get an order from a customer's phone into the kitchen's thermal printer, within 30 seconds of pay, without dropping a ticket during a Friday-night rush.

The approach

A ground-up Next.js 15 stack with four dedicated services: the app (React Server Components for a cold-cached menu), PostgreSQL for orders, Redis for session cache and WebSocket fan-out, and a standalone WebSocket service so the app tier stays stateless. An MCP Print Relay agent paired to the kitchen's network pulls signed jobs from the portal queue and fires Epson ePOS tickets; if the printer goes offline, jobs queue in Redis and retry on reconnect. Everything runs on private infrastructure we own and operate — one operator, one uptime commitment.
