February 2025: Key design-system updates across two repositories. Open Dag planning documentation was updated and the deprecated Form Field Option Label documentation page removed to improve accuracy and reduce confusion. Token modernization and theming were applied across the design system, consolidating and expanding tokens for blockquotes, accordions, links, selects, sidenav, page numbers, logos, task lists, navigation bar, and form field labels. This involved a wave of renames, reordering, and cleanup of token names and CSS class conventions, including new tokens for logo, task list, and a suffix token for Form Field Label. Minor maintenance tasks included removing unused tokens and aligning naming with the Utrecht design language (e.g., blockquote row-gap prefix). Overall impact: stronger design-system consistency, easier theming, reduced CSS churn, and faster onboarding for new contributors. Demonstrated technologies/skills: design tokens architecture and modernization, cross-repo collaboration, naming conventions, token migrations, and documentation discipline.
