I'm a System Administrator with deep expertise in Linux and BSD systems, open source technologies, and infrastructure management. With several years of hands-on experience, I specialize in building, maintaining, and optimizing reliable, secure, and scalable server environments. 🔧 What I do best: Server setup, hardening, and maintenance (Debian, Ubuntu, FreeBSD, OpenBSD, AlmaLinux, etc.) Infrastructure monitoring & observability (Prometheus, Grafana, Zabbix, ELK stack) Virtualization & containerization (KVM, Proxmox, VMware, Docker, LXC) Network configuration, firewalling, and troubleshooting (iptables, pf, WireGuard, OpenVPN) Storage management (ZFS, Ceph, RAID, LVM, NFS, iSCSI) Automation & scripting (Bash, Ansible, cron jobs, systemd) Experience with self-hosted LLMs and AI infrastructure (GPU/CPU-based deployments) 💡 I'm passionate about open source solutions and take a security-first, performance-conscious approach to infrastructure design and administration. Whether it's deploying a new service, recovering a broken system, or tuning your observability stack—I deliver results that are clean, maintainable, and production-ready.
Let’s work together to make your infrastructure faster, smarter, and more resilient.
