Frontend (React) overview

Frontend React specialization focuses on building rich, interactive browser UIs using the React library and its surrounding ecosystem. Core skills include component architecture, React hooks, state management (Zustand, Redux Toolkit, Jotai), styling approaches (Tailwind CSS, CSS Modules, styled-components), and testing with React Testing Library and Vitest. The specialization extends into meta-frameworks (Next.js, Remix, Vite-based SPAs), performance optimization (memoization, code-splitting, virtualization), and accessibility. It is closely adjacent to the Full-stack TypeScript specialization when a backend is co-located.
