About

Building production systems that scale

I'm a Backend Engineer with 4.5+ years of experience building and hardening production APIs, microservices, and event-driven systems. Currently at Neutrinos in Bengaluru, I work on Node.js/TypeScript APIs for an enterprise insurance platform, focusing on security, performance, and Kubernetes deployments.

My expertise spans managing Kafka producers and consumers processing 100K+ events/day across 21+ microservices, optimizing MongoDB aggregations to improve throughput by 5x, and implementing GraphQL Federation gateways that reduced production incidents by 60%.

I've delivered backend infrastructure for platforms serving 15K+ active learners and built offline-first sync systems with conflict resolution for classrooms with unreliable connectivity.

I transitioned into software engineering from a mechanical engineering background, completing a Full-Stack Web Development certification from Masai School in 2021. Starting with my first backend role at Lead School, I've grown from building REST APIs to owning microservices architectures and leading technical design.
