I've built and owned Java/Spring Boot microservices for BBPS, NPCI's national bill payment platform, covering payment initiation, bill fetch, regulatory reporting, and biller reconciliation from requirements through production.

For Billion A Day, I re-architected BBPS Core to support 1 billion daily transactions by redesigning Kafka streaming, applying Redis multi-tier caching, and horizontally scaling 12 microservices with a zero-downtime cutover.

At HCLTech, I architect and deliver cloud-native WMS microservices for three enterprise clients, owning distributed-system design through zero-downtime production deployment. I build high-throughput REST APIs with Java 17, Spring Boot, Hibernate/JPA, Redis, SQL optimization, and CI/CD improvements across Git, Maven, and Jenkins.

I focus on secure, event-driven backend systems in regulated BFSI environments, using Kafka, Spring Security, JWT, OAuth2, Elasticsearch, and automated testing to improve reliability, observability, and delivery quality.
