At PhonePe, I engineer Spring Boot microservices for the Money Management platform, supporting onboarding, pricing, bookkeeping, and settlements. I reduced p99 latency on high-traffic REST APIs from 2 seconds to below 70 milliseconds and cut MySQL query latency by 30% at peak traffic.
I also scaled ordered Kafka processing to 2M+ financial events daily with duplicate-safe consumption, and optimized consumer throughput while reducing instance count. In my Foodwise project, I built an event-driven incident platform with persistent workflows, semantic retrieval over operational documents, and retry-safe inventory operations.
