Cybersecurity Professional

Building secure systems through hands-on experience, continuous learning, and ethical practices.

About Me

I’m a cybersecurity and network administration enthusiast with a passion for understanding systems deeply and protecting them with purpose. I believe that real knowledge comes from doing — which is why I’ve built a personal lab environment to replicate professional scenarios. From setting up Active Directory to simulating brute-force attacks, I spend time learning, breaking, and securing.
