What I'm looking for

I'm looking to build and modernize enterprise backend systems, especially Spring Boot microservices and Kafka-based event-driven platforms, while using AI-assisted development to improve delivery and maintainability.

At Tata Consultancy Services, I migrate legacy COBOL applications into production-ready Spring Boot microservices, translating copybooks and AI-generated pseudo-code into maintainable Java services.

I design Kafka producers, consumers, topics, partitions, and consumer groups for fault-tolerant, high-throughput event-driven communication. I also use GitHub Copilot and Claude to automate code refactoring, library conversion, and framework migration.

Previously at Infosys, I built RESTful APIs and scalable microservices for high-volume investment-management transactions, supported releases through Jenkins pipelines, and resolved production incidents using AWS CloudWatch and root-cause analysis.
