Worked as a freelance Senior Server Administrator helping clients design, deploy, and secure Linux-based server, virtualization, and network infrastructure. My work included Proxmox VE setup, OPNsense firewall configuration, VLAN/network segmentation, VPN and remote access setup, DNS filtering, Docker-based service deployment, monitoring, backups, and server hardening. I also worked with AI-ready home lab and server environments, including Proxmox virtualization, GPU passthrough planning/configuration, vGPU-ready setups, Ceph storage concepts, high availability planning, and scalable infrastructure design for self-hosted AI tools and automation workloads. I deployed and managed services such as n8n, AdGuard Home, Vaultwarden, Nginx Proxy Manager, Uptime Kuma, Samba file servers, dashboards, and other self-hosted applications. Key achievements included building secure home lab infrastructures, isolating services for better security, preparing AI-ready Proxmox environments, configuring backup and restore workflows, hardening SSH and admin access, improving monitoring visibility, and creating clear technical documentation for clients.
