Segmented Cybersecurity Homelab
Built with Proxmox, VLANs, OPNsense, Pi-hole, WireGuard, and Windows/Linux systems to practice realistic attack and defense scenarios.
About Me
I am a recent graduate of Davenport University with a bachelor’s degree in Cyber Defense. I currently work in IT support, where I troubleshoot and maintain Windows and Linux systems in a production environment.
My focus is on incident response, defensive security, and practical infrastructure skills. I actively build and maintain a hands-on homelab using Proxmox, OPNsense, Security Onion, and Active Directory to design segmented networks and simulate real-world attack scenarios.
I take a learn-by-doing approach through building, breaking, securing, and documenting environments that reflect real enterprise networks.
