User Experience & Design Challenges
User Experience & Design challenges put you inside the work of making products people actually understand and enjoy. You'll develop skills in Design Thinking, User Research, and Wireframing, move ideas into Figma, and shape Interaction design with strong Visual Hierarchy.
From there you'll handle the harder edges — Usability Testing, Heuristic evaluation, Accessibility (WCAG 2.2), and Service design — scaling up to Design systems, Design system stewardship, and Information architecture for AI surfaces the way mature product teams actually do. Each challenge you solve earns a verified credential you can share with recruiters.
