  • Strong TypeScript skills (generics, strictness, types-as-design).
  • Deep experience with modern tooling: Vite, Webpack, Babel, SWC, npm/pnpm.
  • Advanced CSS architecture (CSS Modules, CSS-in-JS, utility frameworks) and responsive design.
  • Proficiency in testing with Jest, Vitest, React Testing Library, Playwright, and Cypress.
  • Accessibility expertise: WCAG, ARIA, keyboard navigation, and screen-reader considerations.

  • Must have proficiency using AI-assisted tools (e.g., GitHub Copilot) for implementation and debugging.

Preferred Skills

  • Experience with monorepos and secure client-side patterns (auth flows, token handling).
  • Strong background in API integration strategies including pagination and caching.
