About me

I'm an IT Support Specialist with hands-on experience supporting end users, managing Microsoft 365 and Active Directory accounts, troubleshooting Windows environments, and providing remote technical assistance across multiple programs.

My foundation in network administration and security shapes the way I approach IT: understand the system, reduce risk, document the solution, and make technology easier for people to use.

VoaxSec is where I document that work through practical tools, networking projects, and a growing cybersecurity lab focused on defensive security, analysis, and automation.
