Real-Time Monitoring & Control Platform

Sole backend and systems engineer. Owned architecture, implementation, and deployment. Designed the WebSocket Pub/Sub layer, Golang services, and React dashboard. Coordinated with hardware team on data ingestion.

A rail maintenance company needed real-time visibility and control of 20+ laser-equipped vehicles operating across multiple sites. Legacy systems were fragmented, unreliable, and couldn't support the operational tempo. Data was siloed. Downtime meant lost productivity and safety risk.

Designed and built a unified platform from the ground up: WebSocket-based Pub/Sub for real-time data streaming, Golang services for high-throughput processing (2,000+ requests/minute), React dashboard with map integration and live tracking. Deployed on AWS ECS with Redis for caching and SQS for async workloads. The system now provides a single pane of glass for operations.

• WebSocket Pub/Sub architecture for high concurrency
• Golang services processing 2,000+ requests/minute
• React dashboard with map integration and real-time tracking
• Microservices on AWS ECS with Redis and SQS
• From zero to production
