About

I am an IT & Security Engineer operating on the principle: "To learn defense, one must master offense." I have a strong foundation in designing, implementing, and defending enterprise infrastructures. With hands-on experience in systems administration (Linux & Windows Server), network configuration, and virtualization (Proxmox VE, Docker), I build "secure-by-design" architectures that eliminate vulnerabilities from the hardware level up.

I am passionate about digital sovereignty, open-source enterprise solutions, and creating autonomous, self-sufficient IT environments that minimize external dependencies. I bridge the gap between low-level system understanding and enterprise-scale defense architectures.
