At Airtel Payments Bank, I architected authentication and Server-Driven UI experience layers, including a zero-trust framework and a custom orchestration layer that serves APIs under 100ms. The SDUI caching strategy reached a 97%+ cache hit rate in CUG.
I evolved the bank’s 2FA platform to support 75M+ active users at around 2,000 TPS, and developed device-bound authentication with SIM binding and biometric challenge-response. I also established a cross-team risk-response pattern that secured 3,000+ accounts daily and was later adopted by other teams.
Earlier, at Nagarro, I built a real-time Anti-Fraud Gateway and AML screening pipelines. My work also spans investment banking platforms, cloud-native data systems, and core banking delivery across India, APAC, EMEA, and the US.
