Worked on the PatternFly.org repository to deliver the 6.6 release notes and implement UI and compatibility improvements focused on business value and documentation quality. Used JavaScript and Markdown to rework release notes, resolve build-time formatting issues, and introduce unified AI design guidelines aligned with PatternFly and RHDS standards. Applied React and UI/UX design skills to enhance cross-browser compatibility, including Safari-specific fixes and visual refinements across components. Collaborated with cross-team authors to integrate feedback, finalize version references, and ensure consistency in documentation. This work stabilized the release narrative and reduced deployment risk for developers and stakeholders in upcoming PatternFly releases.
