I’m an experienced Security Architect specializing in cybersecurity strategy, risk management, and secure architecture across distinct Information Technology (IT) and Operational Technology (OT) environments. Leveraging decades of experience in programming, IT operations, and practical cybersecurity implementation, I help organizations align security initiatives directly with their core business objectives.

Additionally, as an Independent AI Researcher, my theoretical work emphasizes ethical and responsible AI applications, algorithmic innovation, and the intersection between AI and cybersecurity. I remain deeply committed to continuous learning, open collaboration, and contributing insights through teaching, writing, and thought leadership.
