About

A bit about me

I'm a backend engineer with around four years of experience building and operating services in production. At Flipkart, I work on domain migrations and shared libraries used across a large microservice ecosystem.

I'm interested in clear service boundaries, safe rollouts, performance under load, and tooling that helps teams ship changes without disrupting live traffic.

Focus areas

Microservices & DDD
Event-driven systems
Rate limiting & traffic control
Canary / controlled rollouts
JVM performance & observability

Assets Engineering

July 2025 — Present

Bengaluru, India

Owned backend components of a service migration from a monolith to domain-driven microservices, defining Kafka and TiDB integration contracts for a zero-impact pre-production rollout.
Built a load-test request-isolation library with end-to-end HTTP-to-event-streaming propagation across 20+ backend services, keeping performance-test traffic out of production consumers.
Resolved Kubernetes OOMKills blocking performance testing by analyzing 1,000+ JVM thread dumps; identified ~1,100 idle ScheduledThreadPoolExecutor threads, reduced per-pool caps from 100 to 15, cut pod thread count by 76% (1,100 → 265), and doubled sustained throughput from 75 to 150 QPS.
Created an annotation-driven distributed rate-limiting library with Bucket4j and Redis, including shadow-mode rollout and dimension-based QPS caps on critical APIs.
Led adoption of an attribute-based canary-routing platform across 40+ microservices using a JVM agent on Kubernetes, with dynamically configured routing rules for targeted production rollouts.
