Message

At BharatPe, I build backend payment systems, including a transaction search platform for 600M+ transactions and a UPI auth notification service processing 20M+ transactions daily. I also shipped on-demand settlement APIs and Kafka consumers for a feature generating Rs. 6 crore in annual revenue.

I’ve improved fraud-check latency from 213ms to 36ms and reduced MySQL CPU utilization by 30%. I also led MongoDB migrations across five clusters and developed a self-service platform that automates 76% of manual DevOps requests.
