About

Backend Java Developer with 3 years of experience building production-grade payment systems for Tier-1 UK banks (Barclays, NatWest) at TCS. What I've worked on: → High-volume payment processing (Faster Payments, CHAPS) handling 10K+ bulk transactions per cycle → Multi-layer API security — mTLS, JWT, JWS — for FCA-regulated banking environments → Loan Origination System that reduced manual dependency by 70% → Reusable Open Banking microservices deployed across 3 banking clients Currently leading a small team of 3, owning end-to-end delivery of backend microservices in production. Outside work, I've built Tree-It — a live full-stack project management tool (React + Spring Boot + PostgreSQL), and have solved 1000+ LeetCode problems with strong medium-level proficiency. Looking for backend engineering roles in product companies, preferably in fintech or distributed systems space. Open to Bangalore-based or remote opportunities. Tech: Java 17 · Spring Boot · Kafka · RabbitMQ · mTLS · JWT · AWS · Docker · PostgreSQL
