Worked on the oxc-project/oxc repository to implement and integrate the ESLint prefer-arrow-callback rule with autofix capabilities, enhancing the linter’s ability to enforce arrow function usage for callbacks. Developed in Rust, the solution included support for options like allowNamedFunctions and allowUnboundThis, and featured robust logic to handle .bind(this) chains, optional chaining, and parenthesized callbacks. Validation was performed using upstream ESLint tests, with results and improvements documented for maintainability. This work streamlines code refactoring, promotes consistent coding style, and reduces manual intervention, leveraging skills in linter development, Rust, and ESLint to improve onboarding and codebase quality.
