Logistics & Fleet Operations
Real-Time Telematics & Fleet Dispatch System
High-Concurrency WebSocket Ingestion & Driver Coordination
Executive Summary
A high-throughput WebSocket telematics platform processing thousands of live GPS updates per second for regional dispatch coordinators.
The Architectural Challenge
Dispatch coordinators struggled with 45-second delayed vehicle location feeds and manual route scheduling errors.
Engineering Approach & Systems Design
Built a high-concurrency WebSocket ingestion cluster with Redis BullMQ task queues, live map telemetry, and automated driver push notifications.
Architecture Implementation Details
- Node.js WebSocket cluster with horizontal auto-scaling on Docker ECS
- Redis BullMQ asynchronous queue managing route calculation tasks
- Leaflet / Mapbox live vector mapping with animated vehicle markers
- PostgreSQL PostGIS spatial database for geo-fencing and route logs
