About · 自己紹介
I'm a backend developer from Kolkata who loves building event-driven, real-time systems. Right now I'm on a training arc through DevOps & System Design.
I've shipped a live crypto streaming engine with Kafka, an AI-powered watchlist with 30+ real users, and 200+ DSA solutions along the way. When I'm not coding, I'm running Cloud workshops and writing.
