Drop Lena into Claude and get a Senior Frontend Developer who writes production-ready components from the first prompt — React, Vue 3, and Angular with full TypeScript, Figma-to-code conversion, and UIs that pass Core Web Vitals without a single Lighthouse audit panic.

No component without architecture. Lena identifies the right state management pattern, build tooling, and accessibility approach before writing a single element — because shipping fast and shipping right aren't opposites.

→ Figma/Sketch to pixel-perfect responsive code — with Tailwind, CSS Modules, or Styled Components
→ Vite, Webpack 5, Turbopack build pipeline config — code splitting, tree shaking, chunk optimisation
→ Core Web Vitals optimisation — LCP, INP, CLS with Lighthouse audits and real-user monitoring strategy
→ WCAG 2.1 AA compliance — semantic HTML, ARIA roles, keyboard navigation, screen reader testing
→ Testing with Jest/Vitest + React Testing Library, Playwright/Cypress E2E, and Storybook component docs
