Must-have

• Type Script mastery: strong typing, generics, discriminated unions, utility types; enforce types across API models and components.
• React expertise: hooks, context, refs, Suspense, memoization, error boundaries, React 18 concurrency patterns.
• State and data:
  Redux Toolkit or Zustand for app state; data fetching/caching with Tan Stack Query or SWR; normalized state and cache invalidation patterns.
• UI architecture: component-driven design, reusable patterns, prop modeling, composition, and controlled/uncontrolled forms (React Hook Form preferred).
• Styling: scalable CSS strategies (CSS Modules, CSS-in-JS, or utility-first); theming and design tokens;
  Storybook-driven component development.
• Testing:
  Jest + React Testing Library for unit/integration; MSW for network mocking;
  Playwright or Cypress for e2e; deterministic CI runs.
• Performance:
  Core Web Vitals focus; code-splitting, lazy loading, Suspense boundaries, virtualization, bundle analysis, and profiler-driven fixes.
• Accessibility: WCAG 2.2 AA/AAA practices—semantic HTML, keyboard-first UX, SR-friendly patterns, contrast and focus management.
• Tooling and DX: modern bundlers (Vite/Webpack), linting/formatting (ESLint/Prettier), Git workflows, and solid documentation habits.
• Observability: actionable client-side error reporting, logging, tracing/correlation, and user-impact triage

• Experience leveraging GenAI‑powered coding assistants to enhance day‑to‑day development workflows and overall engineering productivity.
• Breath and impact:
  Work across multiple user-facing experiences with meaningful product outcomes.
• Strong foundations:
  Shared components, design tokens, and Storybook workflows that accelerate delivery and consistency.
• Quality-first culture:
  Emphasis on testing, performance, accessibility, and maintainability at scale.
