During October 2025, contributed to the oxc-project/oxc repository by developing and integrating the no-param-reassign rule for the OxLint linter. This work involved porting functionality and configuration options from ESLint, leveraging skills in AST manipulation, JavaScript, and Rust to ensure compatibility and maintainability. The rule was thoroughly tested and registered in the OxLint catalog, enabling enforcement across multiple projects and reducing the risk of unintended parameter mutations in codebases. By focusing on feature delivery and robust test coverage, the contribution improved code safety and aligned OxLint with industry best practices for linter rule development and code quality assurance.
