About

I build backend systems that move money across borders — reliably, securely, and at scale. As a Java Backend Developer at NPCI for 3+ years, I've contributed to international UPI and RuPay settlement infrastructure, working on reconciliation workflows, multi-currency processing, and event-driven distributed pipelines using Java, Spring Boot, Kafka, PostgreSQL, and Redis. I enjoy solving hard backend problems — whether it's optimizing a slow query, debugging a production incident at 2 am, or designing a system that needs to handle thousands of transactions without missing a beat.
