Worked on the Buck2 and Buck2-prelude repositories to enhance Python static extension support across multiple Python versions, focusing on cross-version compatibility and build system configuration. Leveraged C++ and Python to unify initialization logic, streamline conda and stock CPython builds, and remove obsolete code paths, reducing maintenance overhead and minimizing build failures. Updated telemetry and network access tests to run reliably under conda, aligning verification workflows with common CI environments. These changes improved the reliability and adoption of Meta Python static extensions, ensuring consistent behavior from Python 3.12 to 3.14 and simplifying integration with Meta-specific APIs in diverse build environments.
