I am a backend software engineer specializing in high-scale wallet, settlement and payments systems, with hands-on experience building resilient microservices and real-time monitoring stacks. I design end-to-end financial workflows, idempotent settlement logic, and scalable pool-account architectures that support high transaction volumes.

At Play Games24x7 I led core wallet backend efforts, delivered Turbo Rummy and Fantasy variants that scaled to 100k+ games/hour and 150k+ txns/min, and built a reusable physical prize distribution framework while improving financial accuracy to 99.9%. I also automated TDS/tax flows and standardized flows using template patterns to simplify future features.

I own on-call reliability for wallet/settlement systems, implemented Prometheus/Grafana monitoring and Debezium-based connectors, reduced MTTR ~40%, and built Kafka-driven fraud and settlement accuracy monitors that cut settlement errors by 95%+. I seek roles where I can continue improving system reliability, payments accuracy, and scale critical financial services.
