ABOUT ME

I’m a Network & Security Engineer with over a decade of hardening enterprise infrastructure across Riyadh and beyond. My work sits at the intersection of deep technical engineering and practical security architecture.

My toolkit: FortiGate, Palo Alto, Azure Sentinel, AWS — but I go further. I build the tools that monitor the tools. I created NOC Sentinel, a real-time network audit application powered by REST API and FortiGate API keys. I’ve built custom asset management systems, deployed full Zero Trust pipelines, and architected hybrid cloud environments end-to-end.

I document what I learn. I automate what can be automated. I secure what matters.
