Summary
🤩
RockstarMichał Górny is a seasoned software engineer with 19 years of experience and a long-running commitment to open source, having contributed to Gentoo since 2010 and to major projects like CPython, LLVM, libgit2, and Git. He specializes in backend development, build systems, cross-platform compatibility and test automation, with notable work on LLVM/Clang build configurations, Python build and performance fixes, and Gentoo package maintenance for complex toolchains like LLVM. Comfortable across C, C++, Python and build tooling, he improves robustness by fixing edge cases (32-bit datetime handling, SSH credential handling, GPG verification) and by hardening test suites for projects such as pip, setuptools and Pillow. Based in Greater Poland, he combines deep systems-level thinking with pragmatic packaging and CI improvements—an approach reflected in contributions that range from CMake tweaks to nuanced Python packaging documentation. Outside code, he organizes work through the projg2 GitHub org and brings a quietly persistent open-source ethos (and a cat) to every project.
