Worked on improving the documentation and developer experience for the TanStack/router repository over a two-month period, focusing on clarity and accuracy in API route references. Addressed inconsistencies by correcting typos, updating route paths, and removing misleading '/api' prefixes from examples to better reflect actual router behavior. Enhanced the Start server routes documentation by eliminating outdated redirect notes, which reduced onboarding friction and potential integration errors for new users. Employed skills in API design, technical writing, and Markdown to ensure documentation aligned with project standards, resulting in clearer guidance and improved maintainability for developers integrating with TanStack/router.
