Hello! 👋

I'm Semere M. Mebrahtom

DevOps & Software Engineer

About Me

I am a software engineer and former Linux system administrator currently studying at 42 Berlin and pursuing a Master of Cyber Security at IU International University of Applied Sciences. With a solid foundation in computer engineering and hands-on experience administering secure Linux infrastructure, I specialize in automating workflows using Ansible, Docker, and Proxmox, as well as developing robust, high-throughput backend systems. I am passionate about peer-learning environments, infrastructure-as-code, and network security.

Projects

01

Portfolio Website & Homelab

Personally administered VPS running NixOS on Proxmox with a fully declarative, flake-based configuration — infrastructure defined entirely as code, with the complete system state reproducible from version-controlled config rather than manual setup. Features a self-hosted Forgejo Git server for CI, and a WireGuard VPN for secure remote access.
