I lead enterprise security automation programs that scale across teams and tools.

At TransUnion, I lead a global security automation team designing and delivering enterprise security capabilities.

I led a SOAR migration from IBM QRadar to Splunk in one year, despite a two-year scope and resource constraints. We delivered 100+ automated playbooks, integrated 15+ security tools, and enabled multi-team contribution that reduced feature delivery from months to days.

My 20-year career began in DevOps and SDLC, including CI/CD pipelines, infrastructure design, configuration management, software delivery, monitoring, and production platform engineering.

I'm comfortable contributing in code reviews and presenting roadmaps to senior leadership. I've hired and developed engineers, owned budgets, and independently explored a patent-pending unified cybersecurity platform for privacy-preserving AI and compliance automation.
