Message

At SAIT, I teach OT/ICS cybersecurity through hands-on work with industrial protocols, SCADA systems, and Schneider Electric control hardware. I developed Splunk detection labs and real-time operational monitoring exercises for industrial scenarios.

I also deliver training in vulnerability management and OT compliance, using tools such as Nessus, OpenVAS, Wazuh, and Zabbix. My instruction covers standards including IEC 62443, NERC CIP, NIST SP 800-53, and ISO 27001.

Previously, at Best Buy, I conducted vulnerability assessments and monitored security events using Nessus, Rapid7, Splunk, and ServiceNow. At eClerx, supporting the Comcast client, I monitored SIEM events and updated incident playbooks; I also hold CompTIA Security+ certification.
