I've built and optimized high-scale Java microservices for enterprise banking clients including HSBC, Truist, and RBS, supporting millions of users and 10M+ daily API transactions.

At LTIMindtree, I maintained 99.95% availability across 23 Dockerized Kubernetes microservices, secured 2–5M+ daily requests with Spring Security and JWT, and managed consumer-facing APIs through Kong API Gateway.

Across Cognizant and Tata Consultancy Services, I developed Spring Boot services, REST/SOAP and GraphQL APIs, Spring Batch pipelines, and resilient distributed workflows for banking transaction and account-processing systems. My performance work reduced batch execution time by 20% and integration defects by 25%.

I also build event-driven products, including an emergency blood donation platform using Spring Boot, Kafka, Redis, geolocation matching, and real-time donor alerts. I care about reliable delivery through TDD, CI/CD, SonarQube, observability, and practical knowledge-sharing with engineering teams.
