Problem
Manual order routing and static menus caused delays during peak hours and made it hard for owners to compare branch performance.
Solution
QR-first ordering with real-time order state, dedicated kitchen UI, and centralized dashboards for menu and branch management.
Overview
Restaurant chains needed a single product to replace paper menus, fragmented POS add-ons, and spreadsheets for owner reporting.
Built a multi-tenant SaaS with QR ordering, kitchen display views, and branch-level analytics so owners see throughput and bottlenecks without calling each location.
Firebase supports push updates to kitchen screens while the core API handles menus, orders, and tenant configuration.

Live ticket queue with status transitions from placed → preparing → served.
Owner analytics

Multi-tenant onboarding
New restaurant brands provisioned with isolated data and branded experiences.
Architecture
