Secure Infrastructure | System Hardening | GRC Strategy

I provide technical rigor and strategic insight to harden enterprise systems, investigate incidents, and ensure operational resilience. As an ISC² Certified Cybersecurity Professional with 120+ verified technical demonstrations and reports, I specialize in transforming complex IT environments into secure, compliant, and high-performance infrastructures.

My work is grounded in a "Proof of Work" methodology—documenting the live execution of repeatable, enterprise-grade security processes designed to eliminate vulnerabilities and ensure audit-ready defense.
