Worked on the flashinfer-ai/flashinfer repository to address a packaging issue related to Python’s Limited API in CPython free-threaded builds. Focused on build systems and CPython internals, the solution involved conditionally disabling the Limited API when necessary, which enabled proper wheel builds and resolved compatibility problems that previously caused deployment failures. This targeted bug fix improved the reliability of Python packaging and ensured smoother downstream integration across different environments. Leveraging expertise in Python and Python packaging, the work strengthened the project’s compatibility strategy, supporting broader platform goals and enhancing the stability of deployment pipelines for users and maintainers alike.
