Worked on a comprehensive documentation overhaul for the Microsoft Fabric Chargeback App within the MicrosoftDocs/fabric-docs repository, focusing on improving onboarding, troubleshooting, and maintenance processes. Consolidated and expanded existing content to cover installation, upgrading, setup, visuals, drill-through, data export, and limitations, while removing outdated or redundant information. Enhanced documentation quality by fixing broken links and updating guidance to reflect current best practices. Utilized Markdown and technical writing skills to deliver clear, maintainable public documentation, including new coverage for the Fabric Chargeback Report. The work improved support readiness and ensured future updates could be integrated more efficiently by development teams.
