Worked on the w3c/Guide repository to enhance documentation reliability by addressing two critical hyperlink issues over a two-month period. Focused on improving user onboarding and reducing support queries, the developer identified and fixed broken and outdated links in Markdown-based documentation, ensuring users are directed to the correct Media Types mailing list subscription page and other intended resources. Leveraged technical writing and documentation skills to implement traceable, standards-aligned changes using Git workflows. The work emphasized link integrity and user experience, validating updates to prevent navigation errors and maintain documentation quality, while contributing to a smoother onboarding process for new users.
