Worked on the mirage-project/mirage repository to stabilize and improve the packaging process for Python projects integrating Rust components. Focused on resolving a critical bug affecting non-editable pip installs by ensuring native .so files were correctly bundled and accessible after installation. Leveraged CMake and Python development skills to refine the build process, including adjustments to build_py and __init__.py handling, and introduced gating for native builds to enhance CI reliability. Added comprehensive packaging and installation tests to validate reproducibility and cross-environment consistency. The work emphasized robust integration of Rust with Python, reproducible builds, and smoother downstream releases through improved tooling.
