What I'm looking for

I am seeking a security-focused role where I can leverage incident response, threat hunting, and automation skills to improve defenses, mentor teams, and drive measurable reductions in risk.

I am a senior-level IT Security Analyst with deep experience in security operations, threat hunting, incident response, and automation. I have resolved 100+ service tickets monthly, supported malware analysis, managed DLP policies, and used PowerShell to automate tasks, consistently reducing downtime and improving security posture.

I led deployment and support for over 4,000 remote devices during the pandemic and have applied tools such as Splunk, Sentinel, Qualys, and MECM across Windows, MacOS, and Linux environments. I mentor junior staff, collaborate cross-functionally, and am ready to apply proven security expertise to protect and strengthen an organization’s cyber defenses.
