Real-Time Restaurant Management & POS Suite
High-Throughput Order Queue, Kitchen Display, and Inventory APIs (Novel Soft)
The Challenge & Context
High peak-hour order volumes frequently led to kitchen ticket drops, inventory count desynchronization, and network timeouts during concurrent point-of-sale transactions.
Engineering Approach & Architecture
Architected event-driven Express endpoints with clustered SQL Server transaction locks, lightweight JSON serialization, and Dockerized environments ensuring identical behavior across branch locations.
SYSTEM ARCHITECTURE SUMMARY:
Micro-services POS engine running on Node.js and SQL Server with robust transaction isolation.
Key Architecture Highlights
- Sub-50ms API endpoint latency under peak load conditions
- Real-time kitchen order dispatch and status synchronization
- Automated ingredient-level inventory decrementing on order placement
- Docker container deployment across multi-terminal setups
