Summary
🤩
RockstarMichał Górny is a software engineer with 18 years of experience and a long-standing Gentoo and open-source background. He specializes in backend development, build systems, and test automation across high-profile projects including CPython, pip, setuptools, LLVM/Clang, and Git. He’s known for hunting down platform-specific build and test issues—NetBSD and Solaris quirks, 32-bit datetime limits, compiler runtime selection—and for improving packaging and dependency workflows for Gentoo and Python ecosystems. His work bridges low-level compiler/toolchain build configuration and high-level Python packaging and QA, emphasizing cross-platform reproducibility and CI reliability. Active since 2010 and now organizing many projects under the projg2 org, he favors pragmatic fixes and stronger test suites that reduce flakiness in production workflows. He’s an outspoken open-source enthusiast (and, per his GitHub bio, also claims to be a cat).
