CoatCheckk

Smart coat check and locker rental for venues: scan a QR code, pay, and the locker opens. We built it through launch hardening and shut it down in 2026.

What we built

  • A Go backend (connectrpc and Gin) on PostgreSQL and Redis, with a TanStack Start frontend.
  • Tuya IoT lockers, Stripe payments, Twilio SMS, and Resend email.
  • Staff and admin dashboards, reservations, inventory, and cron jobs for event-day operations.
  • Docker Compose with ACME for deploys.
  • A Laravel port of the locker rental side with NFC cards and 90+ Pest tests.

One decision worth noting

Partway through, we moved the Go server's auth from WorkOS to Clerk JWTs so it matched a second backend on Hono and Cloudflare Workers. That meant reworking middleware, token validation, and sessions across two runtimes.

Why it's here

It didn't survive, and I learned a lot from that. Real payments and real hardware taught me things I wouldn't have learned otherwise.
