Message

At Expedia, I own the architecture and roadmap for a $2M enterprise security modernization program, including Zero Trust adoption across 100,000+ endpoints. I also serve as a WAF subject matter expert for high-traffic applications.

I led the migration from Carbon Black to CrowdStrike EDR and implemented AI-assisted alert triage and vulnerability prioritization workflows, reducing MTTR by 20%. I partner with engineering teams to embed security into development pipelines and cloud infrastructure.

At Imperva, I optimized WAF configurations to reduce false positives by 25%, and used AI-driven rule analysis and automated testing to cut security review and validation time by 50%. My earlier work includes product security, enterprise network security, micro-segmentation, and security consulting.
