I'm Dravid Kol, a backend engineer who designs event-driven systems — Kafka pipelines, gRPC services, and resilient data layers that scale without drama.
Real-time trading on a microservices architecture with a Kafka event-driven pipeline — order matching, market data, and settlement decoupled into independently scalable services.
Scalable transaction backend with real-time updates and Redis/Kafka fraud detection.

Blogging platform with real-time collaboration over WebRTC peer connections.
Designed event-driven backends for real-time trading and payments — Kafka pipelines, gRPC service contracts, and Redis-backed state, with services decoupled to scale independently.
Built trigger-based WebSocket workflows connecting third-party APIs, with AWS Lambda execution and Redis queues for reliable, at-scale fan-out.
Layering multi-agent LLM orchestration onto existing backend services — turning solid, production-grade systems into intelligent, automated ones.
