Open Banking and IAM Architect at Yodlee, architecting an identity platform for 100M+ users and automating provider onboarding with GenAI.

India

Message

At Yodlee, I architect a multi-tenant, multi-region IAM platform that integrates 100+ identity providers and supports 100M+ users. I work across product, security, and platform teams to deliver Open Banking identity systems.

I led a GenAI-driven provider discovery and OAuth integration effort using AWS Bedrock and Cursor IDE, reducing the provider onboarding cycle from about 30 days to about one week. I also redesigned the migration framework to process about 20,000 records in about five minutes without downtime.

Previously at Yodlee, I built Java identity services processing 10M+ security events per month and helped reduce authentication latency by 30%. At Cisco Systems, I modernized enterprise systems into Java microservices and advanced CI/CD and DevSecOps practices.
