What I'm looking for

I seek a strategic SOC or security engineering role where I can lead incident response, improve detections, automate workflows, mentor teams, and drive measurable improvements in organizational security posture.

I am a cybersecurity professional with 7+ years of progressive experience across IT and SOC environments, specializing in vulnerability management, advanced threat detection, incident response coordination, and security automation. I have hands-on experience with SIEM/XDR, EDR, SOAR, vulnerability scanning, malware analysis, and developing detection rules and playbooks that measurably improve security posture.

I have led incident response efforts, mentored junior analysts, administered and tuned security platforms, and produced executive-level reports and actionable recommendations. I seek a strategic role where I can apply my operational expertise to drive resilience, reduce risk, and foster continuous security improvement.
