What I'm looking for

I am seeking a senior security role where I can lead SIEM/detection engineering, drive proactive threat hunting, and contribute to compliance and cloud security improvements.

I am a Senior Security Engineer with 7+ years of experience focused on threat detection, SIEM engineering, and cloud security across healthcare and enterprise environments. I have a proven track record onboarding MSSP and EDR platforms, building custom detections, and leading SOC operations to reduce mean time to detect and lower false positives.

My work includes supporting HITRUST and SOC 2 audits, deploying CSPM solutions, integrating identity providers, and developing detection playbooks and automated response workflows. I have engineered detections and tuned SIEM/EDR platforms to measurably improve analyst efficiency and incident response.

I hold GIAC GMON, CASP+, and Security+ certifications, and I emphasize proactive threat hunting aligned with MITRE ATT&CK, continuous SOC improvement, and practical compliance support to strengthen overall security posture.
