Hi, I'm Rajeev.
I build real-time systems, from .NET to Angular.

• Led a 5-person team on CIAL Airport (ICCC) and a 10-person team on Jagannath (ANPR) over 2 years — sprint planning, design and code reviews, QA coordination and client delivery, while hands-on in the codebase.
• Architected backend services for a city-scale platform — 4,000 cameras, 3,000 streetlights, 1,000 underground sensors and 1,500+ tracked vehicles — integrating an external AI vision-inference service with health checks.
• Built 4 platform modules (ANPR, Actions, Logging, Events) and a Redis caching layer that eliminated repeated per-request database lookups and cut hot-path latency.
• Scaled the event-driven ingestion pipeline on RabbitMQ/MQTT from ≈40 to 100+ events/sec at 99.5%+ delivery success by cutting message payload size, with idempotent consumers and ack/nack retries.
• Diagnosed and fixed production performance issues — profiled memory and CPU on deployed systems and removed a single-threaded bottleneck, raising throughput 70 → 300+ frames/sec.
• Built secure REST APIs, gRPC services and Angular apps on a Facade-based layered architecture, including a real-time GIS map with live vehicle tracking and route trails from GPS telemetry.
• Owned the product's Windows and Docker releases, automating builds and packaging with GitHub Actions; products cleared STQC and CDAC security certification (Government of India).

Shipped .NET Core REST APIs and Angular features across backend and frontend modules.
