Problem
The challenge was designing one mobile app that feels simple for a guest scanning a table, while still supporting operational roles for waiters, managers and super admins with reliable order status, pricing, promo and QR flows.

Solution
YallaOrder is a multi-role QR ordering platform for dine-in service. Managers create tables, QR codes, menu categories, products, promo codes and staff accounts; guests scan a table QR code, order from the mobile app, and track the order while waiters manage live service status.
Result
The project became a complete mobile ordering MVP with real screenshots, seeded demo data, backend health checks, daily logs, dynamic Expo API host detection and a strong base for restaurant ordering or POS-connected products.
