AeroCodix High-Throughput Point of Sale (POS) & Inventory Engine
An ultra-responsive cloud POS application built for retail shops, supermarkets, and wholesale businesses requiring 300ms billing cycles, multi-warehouse stock auditing, offline resilience, and daily P&L reporting.
The Challenge: Slow Checkout Lag & Inventory Stockouts
The retail chain was suffering from constant checkout line bottlenecks, inaccurate stock counts between branch stores, and loss of business during internet drops:
- ✕5 to 10-second latency per transaction on their legacy web-based POS software.
- ✕Frequent out-of-stock scenarios due to delayed inter-branch inventory updates.
- ✕Total billing stoppage whenever branch broadband connections faced downtime.
- ✕Lack of real-time visibility into cashier cash drawers and daily profit margins.
The AeroCodix Solution: Offline-First Edge POS with Cloud Sync
We engineered an ultra-fast client-side POS running on Electron / React with an embedded IndexedDB/SQLite cache, coupled with a high-throughput backend running on Redis pub/sub and PostgreSQL.
- ✓Sub-second barcode search indexing 100,000+ items directly in memory.
- ✓Seamless offline billing mode that queues transactions locally and syncs automatically when reconnected.
- ✓Integrated thermal receipt printing (ESC/POS) and cash drawer kick drivers.
- ✓Automated multi-branch stock transfer requests and low-inventory reorder alerts.
