During a one-month period, contributed to the codemod-com/codemod repository by refactoring the Sourcemap Option creation logic in the CLI. The work focused on replacing traditional if/else statements with the then_some method in Rust, resulting in clearer and more maintainable code while preserving existing CLI behavior. This backend development effort established a reusable pattern for Option construction, which simplifies future enhancements and reduces the risk of regressions. By aligning the codebase with functional programming practices, the changes improved onboarding for new contributors and lowered long-term maintenance overhead, positioning the project for more efficient future development and feature expansion.
