I’m a Software Development Engineer Intern building production-grade, event-driven backend systems. At Razorpay, I designed a Kafka-based asynchronous bulk reconciliation architecture that replaced synchronous HTTP processing and improved fault isolation, scalability, and observability.

I also implemented a Redis-based distributed idempotency mechanism to guarantee exactly-once execution for scheduled workflows, introduced backward-compatible refund initiation visibility in dashboard APIs, and strengthened settlement reliability by building Service-Level Integration Testing to raise coverage from 0% to 80%.

Beyond core backend work, I resolved a critical production data integrity issue by redesigning multi-service response aggregation to prevent overwrite-based data loss, added runtime-safe validation to eliminate service panics, and contributed to the Go 1.26 upgrade with end-to-end compatibility and regression checks. In parallel, I built an AI-powered travel planning platform with React and Gemini API integrations, and I’m energized by solving hard systems problems—evidenced by my LeetCode Knight rating and 2000+ problems across platforms.
