Senior Principal Linux/AI engineer specializing in secure enterprise systems.
What I'm looking for
I am a Senior Principal Linux/AI Engineer and technical author with over 20 years securing and hardening large-scale Linux, z/Linux, and enterprise mainframe environments. I combine deep technical expertise in digital forensics and penetration testing with strategic security architecture.
I've led security strategy and automation for thousands of servers on IBM mainframes, engineered remediation frameworks, and authored compliance tooling for DISA STIGs and NIST frameworks. My work integrates AI and LLMOps principles to improve threat mitigation and operational efficiency.
As a published author, I write about algorithmic auditing, sovereign AI on mainframes, private model scaling, and practical prompt engineering. My books and guides translate complex regulatory and technical challenges into actionable enterprise practices.
I hold multiple industry certifications, maintain an active DoD security clearance, and mentor teams on red/blue operations, secure automation, and resilient AI deployment. I seek roles where I can architect secure, audit-ready AI-enabled systems at enterprise scale.
