Who Am I

I self-funded my IT education while working part time, earned my CompTIA A+ and Network+, and built hands-on lab projects from scratch, like setting up enterprise networks, building Windows Server environments, migrating VMs between hypervisors, writing automation scripts, and more. None of it was handed to me, and I got stuck plenty of times but I always found a way through. I'm currently studying for CompTIA Security+ and spending my free time learning new technologies, reading IT related books, and solving rooms on TryHackMe and HackTheBox.

On the work side, I have a year of on-site IT support experience troubleshooting hardware, Windows, software, networks, keeping internal systems running and helping end users. I also have 3 years of experience leading a team of 6 in a high pressure production environment where fast diagnosis and zero downtime was mandatory. That experience taught me how to stay calm under pressure, think systematically, and get things fixed fast, skills that carry over directly into IT.

If you want to see what I've been building, my GitHub has all my projects with full documentation.
