During November 2024, contributed to both the oxc-project/oxc and web-infra-dev/rspress repositories by delivering two features and a bug fix focused on code quality and user experience. Enhanced oxc by adding dedent and outdent support for tagged template expressions in rule generation, leveraging TypeScript and AST manipulation to improve test normalization. Developed a new ESLint rule to discourage array indices as keys in React components, providing actionable diagnostics and suggestions. In rspress, addressed navigation bar reliability by consolidating scroll event handling for consistent behavior across devices. Demonstrated expertise in JavaScript, TypeScript, linter development, and front-end engineering practices.
