Developed cross-platform continuous integration and testing infrastructure for conda-forge/staged-recipes, enabling automated builds and tests across Windows, macOS, and Linux environments, including CUDA support. Leveraged Bash scripting, Python, and YAML configuration to create platform-specific build and test scripts, ensuring compatibility with the lowest supported Python version and improving reliability across diverse environments. Additionally, contributed to prefix-dev/pixi by refining project documentation, specifically removing duplicate entries to enhance clarity and maintainability. The work focused on strengthening repository quality controls, reducing integration risk, and supporting efficient onboarding, with an emphasis on maintainable CI/CD workflows and clear, accurate documentation for contributors.
