What I'm looking for

I seek senior security roles where I can lead cloud and SOC initiatives, drive automation, mentor teams, and ensure compliance while delivering measurable operational improvements.

I am a Senior Security Engineer and IT leader with 19 years of experience designing and operating security infrastructure across hybrid environments. I combine strategic thinking with hands-on execution to deliver secure, compliant, and resilient systems.

At Capital One I led automation and SRE initiatives that cut deployment times by 75%, established SLOs/SLIs, and reduced break/fix tickets through automated patching and remediation. I build SOCs and wrote incident response playbooks at Rally Health, aligning operations with regulatory frameworks.

I founded and operate an IT solutions company providing SIEM, IAM, endpoint security, federal compliance, and Python-driven automation to streamline security workflows and vulnerability remediation. I also deliver training to elevate user security awareness and productivity.

I hold a Master’s in Cybersecurity, am pursuing a PhD in Cyber Leadership, and maintain AWS Solutions Architect certification; I mentor and build collaborative teams focused on technical excellence and measurable security outcomes.
