Summary
Kaustav Chanda is a backend-focused Developer 3 with a proven track record of designing and operating cloud-native, fault-tolerant systems that power real-time, high-availability platforms. With strong C#/.NET expertise, he builds low-latency WebSocket and streaming solutions that handle parallel message flows, resumable large-file transfers, and robust reconnection strategies under strict SLAs. He pairs engineering rigor—100% coverage on critical business logic and CI/CD automation—with pragmatic architecture patterns like plugin/adaptor-driven designs to enable safe extensibility. Experienced across AWS services (ECS/Fargate, Lambda, Kinesis, S3), he also architects production-ready AI-adjacent systems such as RAG pipelines and vector-backed semantic search. Notably, Kaustav blends hands-on implementation with operational ownership, having improved deployment frequency 3x and boosted transfer efficiency in large-file federation PoCs. Based in Kolkata, he aims to grow into a Principal Engineer/Architect role while staying deeply involved in complex backend and distributed-system challenges.
