Fein QR Menu

A two-app product: a CMS for restaurants to compose menus, and a public-facing customer flow. Multi-language, multi-currency, real-time edits, and per-restaurant theming. Built on Supabase with edge functions for hot paths.

The Problem

Restaurants were stuck between printed menus that go stale and generic QR tools that ignore branding, languages, and currencies. Owners needed to change prices in the moment — not reprint menus or email a designer.

The Solution

A two-app SaaS: a menu editor where restaurants compose and theme their menus, and an edge-optimized customer flow that opens straight from a QR code. Multi-language, multi-currency, real-time edits, and per-restaurant theming — all multi-tenant on Supabase.
