Niels Roozemond developed and maintained the Amsterdam/design-system repository over ten months, delivering fourteen features and resolving five bugs. He focused on building robust UI components and icon libraries using React, TypeScript, and SCSS, with an emphasis on accessibility, semantic structure, and maintainability. His work included refactoring navigation and footer components, optimizing SVG assets, and modernizing Sass usage for styling consistency. Niels also improved keyboard navigation, documentation clarity, and platform compatibility, ensuring the design system remained current and easy to adopt. His engineering approach balanced technical depth with practical usability, resulting in a scalable, accessible, and well-documented component library.

June 2025: Focused on design-system polish and icon accuracy. Strengthened Amsterdam/design-system with UI spacing/padding polish and enhanced documentation, plus clarifications for icon documentation and button variants across components and stories. Fixed visual inconsistency by correcting login/logout SVG assignments. Outcome: more coherent design language, clearer iconography/docs, and reduced risk of UI regressions across new pages and stories.

March 2025 — Amsterdam/design-system: Implemented Accessible Tabs Keyboard Navigation by refactoring TabsList to centralize keyboard focus management. Arrow keys now navigate between tabs without changing the active panel, reducing unintended tab switches and simplifying the main Tabs component by removing unnecessary refs/hooks. Fixed bug: Do not change active tab when using arrow keys in panel (#1936) (commit 82bed7a3c14bb7f7f7654782c41e3a96a8e7c828). This work improves accessibility, keyboard UX, and maintainability, with clear commit traceability.

January 2025 — Amsterdam/design-system: Key features delivered, major bugs fixed, overall impact, and technologies demonstrated. Key items include: 1) Platform Compatibility Upgrade: Node.js 22 across the project (updates to .nvmrc and package.json) to align with newer dependencies and performance/security improvements. 2) Tabs Component Accessibility and UI Stability: removed an invalid ARIA role and prevented tab button text wrapping to improve accessibility and visual consistency. 3) Documentation UI Fix: Dialog examples render correctly by adjusting ams-docs-backdrop display within ams-screen for proper documentation visibility. Impact: improved platform readiness for modern dependencies, stronger accessibility, and more reliable documentation. Technologies/skills demonstrated: Node.js version management, ARIA accessibility best practices, UI stability/UX refinements, and documentation hygiene with clear change traceability.
