About

​I am an IT Infrastructure and Operational Technology (OT) Cybersecurity professional with 8 years of experience safeguarding enterprise and industrial control systems (ICS). My expertise lies at the intersection of critical infrastructure reliability and robust security compliance, with a proven track record in high-availability, safety-critical environments.​Having spent nearly 3 years embedded in the Oil & Gas sector as a Control System IT Engineer, I specialize in bridging the gap between traditional IT security frameworks and the stringent operational demands of production environments (PCD/OT). I thrive in managing mission-critical upgrades, ensuring zero-downtime operations, and maintaining strict cybersecurity alignment.​Core Technical Expertise:​OT/ICS Security: Cybersecurity compliance, risk mitigation, and threat awareness in industrial networks.​Infrastructure & Networking: Core switch upgrades, network segmentation, and secure architecture design.​System Engineering: Control system support, high-availability server infrastructure, and complex troubleshooting.​Project Execution: End-to-end technical delivery in high-stakes, regulated environments (e.g., LNG facilities).​I am dedicated to building resilient industrial architectures that protect human capital, environment, and production assets. Always open to connecting with fellow cybersecurity professionals and exploring new technical challenges.
