At Paytm, I build and operate backend services and streaming pipelines serving more than 20 million users. I led the Monthly Statement Flow, delivering Excel and PDF statements, and integrated email and push notifications to improve reliable delivery at scale.
I designed a Kafka-based cashback pipeline processing 426 TPS, created resilient retry handling that achieved 99.9% delivery success, and optimized Elasticsearch queries to improve response times by 30%. I also own deployments, releases, monitoring, and production incident resolution, including zero-downtime rollouts.
Previously at Newgen, I developed medical card generation and MVC-based employee data management for 100,000+ employees. I improved backend data retrieval through query tuning and access-layer improvements, reducing average response time by 75%.
