Secure Infrastructure | System Hardening | GRC Strategy

I provide hands-on security implementation and framework-aligned technical controls to harden enterprise systems, investigate incidents, and reduce organizational risk. As an ISC² Certified Cybersecurity Professional (CC) with 120+ documented technical labs and reports, I specialize in transforming complex IT environments into secure, compliant, and resilient infrastructures.

My work is grounded in a "Proof of Work" methodology—executing repeatable, documented security processes that strengthen systems, mitigate vulnerabilities, and support compliance readiness.
