About

Senior Backend Engineer with 5+ years of experience designing, scaling, and operating high traffic systems at Blinkit (10M+ DAU). I specialise in Python, Go, Kafka pipelines, Postgres, Redis, and building reliable, high performance microservices. I’ve led multiple zero downtime migrations, modernised critical infrastructure, improved system reliability and latency, and delivered high impact product features alongside major cost saving initiatives across compute, storage, and asynchronous workloads. My work spans large scale data pipelines, infra upgrades, and resolving complex production issues including memory leaks, ingress failures, and identifying DB bottlenecks. I enjoy solving hard engineering problems, driving cross team execution, and shipping high impact features that directly shape customer experience and business outcomes.
