About me
I build, harden, and maintain Linux infrastructure — securely, documented, automatable. 10+ years across Debian, RHEL, Arch, FreeBSD. Proxmox (KVM/LXC) with ZFS, full-disk encryption with remote unlock, WireGuard mesh, nftables, hardened mail (Stalwart, Postfix, DKIM/DMARC/SPF), DNS/DNSSEC, CI/CD.
Rare combo: I write firewall rules AND read regulations — GDPR, NIS2, EU AI Act, BDSG.
Also ship production code: Rust for systems, TypeScript/SvelteKit for web. Built a VW Group automation tool that cut errors to zero.
Germany-based. EN/DE. IHK-certified IT Systems Engineer.
