About Me

I'm an IT Support–certified Economics student with 5+ years of hands-on experience in system administration, virtualization (Proxmox, Hyper-V), and network infrastructure.

Skilled in scripting, automation, and server deployment across Windows and Linux environments. I've built and maintained 6-10 production-grade servers with 90%+ uptime using automation tools and Infrastructure as Code (IaC) principles.

Currently pursuing Economics at USI while continuing to deliver scalable, secure, and high-availability infrastructure solutions to clients.
