Senior Systems Architect | Proxmox - Private Cloud & SysAdmin Expert

If you are looking for a reliable, battle-tested Systems Architect to design, secure, or migrate your core infrastructure with zero downtime, you are in the right place. With over 15 years of hands-on experience (since 2007), I act as a Virtual CTO and Infrastructure Custodian for growing businesses. I do not write application code; I specialize purely in hardcore system administration, enterprise networking, and modern self-hosted infrastructure. --- HIGH-VALUE SOLUTIONS I PROVIDE --- ✔ Private AI & LLM Infrastructure: Companies are moving away from public AI due to data privacy. I deploy secure, on-premise AI environments (Ollama, Dify, Open WebUI) using Docker and Proxmox GPU passthrough so your data never leaves your servers. ✔ Sovereign Cloud & "De-Googling": Expert-level deployments of Nextcloud/Owncloud, Mailcow/iRedMail, and SSO Identity (Authentik/OIDC) to replace expensive Microsoft 365 or Google Workspace subscriptions. ✔ Virtualization & HA Clusters: Proxmox VE (High Availability, ZFS, Ceph), VMware migrations, and bare-metal server partitioning. ✔ Enterprise Security & Networking: pfSense/OPNsense firewalls, Multi-site VPNs, Reverse Proxies (HAProxy/Nginx), and strict server hardening. ✔ SysAdmin & Control Panels: Extensive experience managing web servers, optimizing performance, and handling fleets across cPanel, Plesk, AWS, and Oracle Cloud. --- MY APPROACH FOR LONG-TERM CLIENTS --- I specialize in long-term partnerships. I don't just execute basic commands; I analyze your hardware bottlenecks, implement automated monitoring (Zabbix/Grafana) to prevent issues before they happen, and guarantee stable production environments. Let's discuss how we can build a secure, cost-effective, and scalable system for your business.
