Frontend Development Challenges
Frontend Development challenges put you inside the work of building interfaces people actually use. You'll develop skills in HTML & CSS, the DOM, React, and Tailwind, composing interfaces through component composition and wiring up state management.
From there you'll handle the harder edges — design-system architecture, Next.js / Vue app architecture, SSR / SSG strategy, and web performance (Lighthouse, Core Web Vitals) — building accessibility (WCAG 2.2) into every screen the way product teams actually do. Each challenge you solve earns a verified credential you can share with recruiters.
