Worked on the vitejs/docs-cn repository to enhance documentation quality and localization readiness over a two-month period. Focused on improving readability and consistency by standardizing punctuation, spacing, and translation alignment across configuration, guide, deployment, and troubleshooting documentation. Applied technical writing and translation skills to refine Markdown files, consolidating typographical conventions and formatting for Chinese-language contributors. Addressed formatting bugs and normalized list structures, internal links, and API references, which reduced localization friction and streamlined onboarding for new developers. Maintained strong Git hygiene with targeted, descriptive commits, ensuring ongoing maintainability and professionalism throughout the documentation corpus without introducing new bugs.
