I’ve spent 3+ years designing and scaling distributed backend systems across fintech and consumer products. I work across Java/Spring Boot and Go, building microservices, APIs, and event-driven pipelines with Kafka and Redis.

At Swiggy (Recro), I led a backend redesign for a high-scale consent management system using DynamoDB features like conditional locking and idempotency. I also helped scale campaign processing from 400 to 60,000+ recipients per campaign while improving throughput, reliability, and operational stability.

I build service-to-service interfaces (including gRPC) and run full lifecycle ownership—from technical design to deployment and monitoring. I’ve also implemented Go workflows for image-based use cases with asynchronous job orchestration and AWS S3.

Earlier at National Payments Corporation of India (NPCI), I built Java/Spring Boot and Hibernate/JPA backend services and Kafka-based pipelines for millions of banking transactions daily. I improved fraud detection accuracy, and I delivered monitoring and alerting that reduced downtime and incident resolution time.
