What I'm looking for

I seek backend/Java roles focused on scalable microservices, automation, and measurable performance gains in collaborative Agile teams.

I am a Java backend developer with hands-on experience building microservice-based systems, batch processes, and REST integrations for enterprise health insurance products. At Tata Consultancy Services I designed and deployed core batch jobs, advanced EMI payment features, and a reusable Spring logging utility that improved issue resolution and traceability.

My work emphasizes automation, reliability, and performance—replacing manual flows, cutting settlement times from hours to seconds, and achieving a 98%+ payout success rate. I hold a Master of Computer Applications with strong academic performance and a research background in fog vs. cloud performance for inventory management.
