What I'm looking for

I'm seeking a senior cybersecurity leadership role where I can apply my experience leading OT and enterprise cybersecurity initiatives to strengthen operational resilience, reduce cyber risk, and support secure business growth across critical infrastructure environments.

At Corteva Agriscience, I advance OT cybersecurity initiatives across manufacturing and operational facilities, supporting resilience and enterprise security alignment. I work with internal stakeholders and EY consulting teams on governance frameworks, operating models, and standards.

I evaluate and roll out OT security technologies, including Nozomi, CrowdStrike, and Check Point solutions. I also coordinate with enterprise teams on vulnerability management, endpoint protection, and incident response while balancing security improvements with operational continuity.

At ONEOK, I led a five-person Strike Team on network segmentation across 80 operational locations, supporting more than 500 SCADA devices and 6,000 pipeline meters. Secure network transitions were completed with zero disruption to product flow.

At Siemens Energy, I supported NERC CIP-aligned planning, vulnerability remediation, and SCADA cybersecurity integration. I also led cybersecurity responsibilities for a $24M windfarm modernization initiative spanning 14 operational locations.
