Expert-level React proficiency (hooks, component composition, context, rendering behavior, concurrency-related patterns where applicable).
Strong TypeScript skills (types-as-design, generics, strictness strategies) and modern JavaScript fundamentals.
Deep experience with modern front-end tooling: Vite/Webpack, Babel/SWC, npm/pnpm/yarn, monorepos (optional), and build/release pipelines.

Advanced testing practices: Jest/Vitest, React Testing Library, Playwright/Cypress for E2E; test strategy ownership.
Accessibility expertise: WCAG/ARIA, keyboard navigation, screen-reader considerations, and automated + manual a11y testing.
Performance engineering: profiling, bundle splitting, SSR/CSR trade-offs, caching strategies, and Core Web Vitals optimization.
API integration expertise with GraphQL and REST (schema-driven development, error handling, pagination, caching, and client state strategies).
Security awareness for web apps: XSS/CSRF prevention, dependency hygiene, secure auth/session patterns (OIDC awareness a plus).
Observability for the front end: client-side logging/metrics, error reporting, and debugging production issues.
MUST: Proficiency using AI-assisted engineering tools (e.g., Claude Code, GitHub Copilot) to accelerate implementation, refactoring, test creation, and debugging-while validating correctness and adhering to secure handling practices..
