System Engineer at Self-employed
Vienna, Austria
Summary
🤩
RockstarPaul Härle is a seasoned system engineer based in Vienna with 13 years of experience building and operating reliable infrastructure for both enterprises and self-hosted services. Currently self-employed, he combines deep Nix ecosystem expertise—contributing to projects like disko and dream2nix—with practical DevOps and backend engineering skills around CI/CD, containerization, and large-scale migrations. His background includes implementing PCI-DSS Level 1 infrastructures and modernizing complex, long-lived hosting and streaming stacks without downtime. Colleagues know him as a "cloud plumber" who enjoys plumbing together reproducible, declarative systems and solving gritty build-and-deploy problems. He brings a pragmatic focus on automation and build systems, often surfacing non-obvious improvements such as temporary-directory refactors and mount option abstractions that reduce operational fragility.
