About

Senior Backend Engineer with experience building and owning high-scale payment and financial systems in fintech and enterprise environments. Currently working at Razorpay in the Payments (UPI) domain, where I own end-to-end delivery of critical payment integrations and platforms — from system design and backend development to infrastructure automation and production rollout. I’ve led large-scale UPI gateway integrations handling multi-crore daily transaction volumes, built automated onboarding frameworks that reduced setup time from days to minutes, and driven migrations from monolithic systems to microservices to improve scalability, reliability, and deployment velocity. Previously at BNY Mellon, I worked on microservices-based platforms for loan processing and client worth analysis, optimized high-traffic APIs used by tens of thousands of daily users, and built workflow orchestration and data processing systems to improve reliability and operational visibility. I enjoy working on problems involving distributed systems, backend reliability, and system design, and I’m particularly interested in building platforms that operate at scale, handle failures gracefully, and are easy for teams to extend and maintain. I value ownership, automation, and clean engineering practices, and I like operating close to production where engineering decisions have real-world impact.
