About

With over 12 years of experience in software development, I currently contribute as a Senior Software Developer at Cisco, focusing on IAM and SSO engineering. My work involves leading a team to design and deploy robust solutions like Dynamic Client Registration and Client ID Metadata Documents within Duo's global SSO infrastructure. This initiative supports enterprise customers with seamless authentication integration while enhancing security and compliance. Leveraging expertise in data persistence and system reliability, I have implemented innovative mechanisms such as DCR backfilling using Kafka and resolved critical bugs impacting global authentication processes. My mission is to create resilient, scalable systems that empower businesses to operate securely and efficiently in today's complex digital landscape.

Work experience

Senior Software Developer at Cisco, Dec 2024 - Present · 1 yr 9 mos, Bengaluru, •​ IAM & SSO Engineering: Leading a 3-engineer team architecting, hardening, and deploying Dynamic Client Registration (DCR) and Client ID Metadata Documents (CIMD) within Duo's global SSO infrastructure — enabling enterprise customers to seamlessly integrate authentication into automated, agentic workflows while bolstering the authentication pipeline against sophisticated attack vectors and meeting compliance requirements. •​ Data Persistence: Implemented DCR backfilling via Kafka, ensuring persistence occurs only post-user authentication — preventing premature registration state leakage. •​ System Reliability: Resolved a critical IP reputation staleness bug that had exposed every Duo authentication request globally to outdated threat data until server restart — restructured the reputation check lifecycle to eliminate the vulnerability. •​ Technical Evangelism: Delivered internal technical talks on Model Context Protocol (MCP), driving cross-team understanding of agentic integration patterns for enterprise security.
