Architecting Transactional Scale
The Objective
Design a fault-tolerant mobile Point of Sale system capable of maintaining operational integrity in challenging retail environments. The primary directive was seamless hardware integration and a robust hybrid offline mode to ensure zero transaction loss.
The Outcome
A resilient React Native engine backed by a high-throughput API architecture. Achieving sustained transaction rates exceeding 100+ TPS, with seamless background sync protocols when connectivity is restored, ensuring uninterrupted commerce flow.
Hardware Connect Protocol
The mobile client acts as a localized hub, interfacing directly with peripheral retail hardware via low-level protocols, bypassing standard OS bottlenecks for critical path operations.
React Native Core
Cross-platform UI execution with native bridge modules for hardware access.
BLE Printer Gateway
Direct Bluetooth Low Energy integration for thermal ESC/POS commands.
