I build high-throughput, low-latency microservices for e-commerce and fintech platforms.

At Bigbasket, I built BB Sambandh from scratch to modernize vendor onboarding and support the migration of thousands of existing vendors.

I design event-driven microservices with Java, Spring Boot, Apache Kafka, and Vert.x, processing millions of SKU updates daily with sub-100ms average latency. I redesigned catalog ingestion from a six-hour synchronous workflow to a 10-minute asynchronous pipeline and reduced primary database load by 40% through CQRS.

Previously, I improved throughput and reliability for Airtel Money at Comviva and built the ATS recruitment platform at Harman Connected Services. I also mentor teams on distributed systems, lead observability initiatives, and build scalable services on Kubernetes and AWS.
