I lead enterprise security platforms that automate vulnerability remediation, application security, and resilient technology governance.

At Cisco, I lead enterprise security intelligence across vulnerability management, application security scanning, third-party software risk, application resiliency, and policy management for a ~65-member organization. My teams process more than 2 million vulnerabilities daily, achieve 98% effective closure for critical and highly exploitable issues, and reduced new vulnerability creation by 59% through AI-powered IDE remediation and CI/CD-integrated controls.

Previously, I led solution architecture and continuous availability at Visa, where I helped achieve 99.999% availability across critical payment platforms and reduced failover execution from hours or days to seconds. My background spans payment platforms, infrastructure engineering, software development, cloud orchestration, open-source risk, and technology governance at CyberSource, PayPal, Digital River, and Accenture.
