What I'm looking for

I'm targeting roles in back-end development, Java, microservices, full-stack engineering, and distributed systems across industries.

At Nykaa, I engineered back-end enhancements for the Style Exchange feature across Checkout and Payment services, from API development and Low-Level Design documentation through production deployment. I also integrated payment capabilities for PayU and LazyPay and strengthened authentication controls across microservices.

At Bharti Airtel, I architected a distributed tracing framework that propagated trace IDs across 20+ microservices through REST APIs and Kafka. Earlier, at Novus Hi-tech, I delivered fleet management and analytics applications for ADAS and autonomous mobile robot platforms, using Java, Spring Boot, React, and Angular.
