Summary
🤩
Rockstar🎓
Top SchoolTina Müller is an experienced engineer based in Berlin with 14 years of hands-on experience building backends, test and build infrastructures, and automation for open-source and enterprise projects. She combines deep expertise in Perl, Python/YAML, shell scripting and CI with a pragmatic focus on automating repetitive work to save time—often by building tooling such as sophisticated shell-completion generators and a grammar-based YAML parser. A long-term contributor and maintainer in the YAML ecosystem (including libyaml, PyYAML and the official test suite) and to openQA/openSUSE testing frameworks, she brings both QA/test-automation instincts and backend optimisation skills. Colleagues know her for fast bug sleuthing, thoughtful refactors (centralising JSON RPC in os-autoinst), and making developer tools more usable across shells and platforms.
