Overview
An enterprise-grade, ultra-low-latency restaurant operating system that unifies high-concurrency B2B franchise management, multi-station Kitchen Display Systems (KDS), and instant table-side QR ordering into a single, flawlessly synchronized real-time web application.
The Challenge & Solution
Legacy restaurant POS and KDS platforms suffer from crippling polling delays, proprietary hardware lock-ins, and disjointed ordering workflows that cause lost kitchen tickets, table-collision errors, and slow table turnover. We engineered a cloud-native, zero-latency hospitality infrastructure where QR order capture, OTP customer identity verification, Kanban kitchen orchestration, and counter payment settlements execute in synchronized, sub-second harmony.
Architecture
Impenetrable multi-tenant isolation enforced at the database engine layer via strict PostgreSQL Row Level Security (RLS), custom JWT claims, and edge-enforced cryptographic device fingerprinting (`qr_sessions`), guaranteeing absolute data separation across thousands of concurrent restaurant brands.
Telemetry & Outcomes
Bi-directional WebSocket pipelines (`postgres_changes`) backed by self-healing, deterministic polling fallbacks deliver sub-100ms order dispatching to kitchen screens and live table-side status synchronization (`Sent` → `Preparing` → `Ready`) with zero packet drops.
