What I'm looking for

I seek a senior cybersecurity role where I can lead incident response, improve threat detection, secure cloud and OT environments, and mentor cross-functional teams.

I am a seasoned cybersecurity professional and U.S. Army veteran with broad experience in security operations, threat intelligence, and incident response across enterprise, cloud, and OT environments. I have led global incident response efforts, improved threat detection capabilities, and implemented phishing mitigation and insider-threat programs for Fortune-level and multinational organizations.

My background combines operational discipline from military service with hands-on technical expertise in SIEM, IAM, cloud security, and forensic investigation; I author security documentation, build playbooks, and collaborate cross-functionally to reduce risk and harden enterprise systems.
