Contributed to the termux/termux-packages repository by developing and integrating PyRefly, a fast Python type checker and language server, as a new package for Termux. This work involved writing Rust and Shell scripts to create reliable build processes and applying compatibility patches to ensure smooth operation within the Termux environment. The packaging workflow was completed to support straightforward installation through the Termux package manager, enhancing the Python development experience on mobile devices. Emphasis was placed on reproducible builds and maintainable patch management, laying a foundation for future tooling improvements and supporting robust Python code quality within the Termux ecosystem.
