UpperDeck serves a mixed local + tourist crowd. Customers needed a fast, mobile-first menu: no app store, no QR-redirect ad farms, just the menu. Staff needed inventory + order management that didn't require a manager to be the only person who can change a price.

Two front-ends, one Postgres. Supabase RLS handles the role boundary cleanly: line cooks can mark items 86'd, the manager can adjust pricing, the owner can see what sold yesterday. Orders flow to a Telegram channel the back-of-house already lives in.

Built in five weeks. Live the day the lease started.
