At Flipkart, I architected a GenAI/LLM-powered on-call orchestration system for automated incident triage, reducing MTTD by 90%. I also built a real-time metrics library for operational visibility.
I reduced COD refund P99 turnaround time by 99.17% by architecting QR-based back-to-source and integrating Instant Refund capabilities with external banks and payment gateways.
At Flipkart, I built balance management and card-linking capabilities for the My Accounts EGV module, and designed a distributed rate limiter that reduced rate-limit breaches by 90%. I also spearheaded a JDK 8 to JDK 21 migration across production microservices and onboarded hermetic testing.
Earlier at Flipkart, I built Java backend microservices and REST APIs for payments, refunds, recharge, and bill-payment workflows. I integrated Paytm webhooks for asynchronous refund updates, reducing latency by 80%, and implemented fraud detection and access control for Refund APIs.
