About

Backend Software Engineer with experience building and scaling fintech platforms across credit, payments, and onboarding domains. I currently work as a Software Development Engineer II at Super.Money (Flipkart Group), where I design and build distributed backend systems powering high-traffic consumer journeys. I have led development of high-performance orchestration engines, Backend-for-Frontend (BFF) platforms, and experimentation frameworks used in co-branded credit card onboarding and offer evaluation. My work has contributed to 10× performance improvements, P99 latency around 230ms, and systems supporting 50K+ daily applications and 21M+ total user journeys. I have also worked on building credit score pipelines, fixed deposit journeys, and reliability-first backend systems with strong observability and alerting, supporting hundreds of thousands of issued cards. I hold a B.Tech in Electronics and Electrical Engineering from the Indian Institute of Technology (IIT) Guwahati. I enjoy working on distributed systems, system design, and performance optimization, and I’m always interested in building products that operate at scale and have real user impact. Tech: Java, Distributed Systems, Microservices, Spring Boot, REST APIs, MySQL, Redis, GCP, Kubernetes, Docker
