Descripción de la oferta

The web app you’ll be touching is a mature React codebase serving thousands of daily users. My immediate goal is to complete a redesign sprint, add several data-heavy views, and squeeze out every last millisecond of render time. You will receive Figma files, an API contract, and access to our private GitHub repository. From there, your mission is to translate the designs into modular React components, keep state predictable, and leave the codebase cleaner than you found it. A typical day will include refactoring class components into modern hooks, wiring endpoints through our existing data layer, and writing unit tests so the CI pipeline stays green. Deliverables • Pixel-perfect, responsive React components matching the supplied designs • Integrated API calls with error and loading states fully handled • Unit tests covering new logic (Jest + React Testing Library) • A concise pull-request description explaining key decisions Acceptance criteria 1. All new components render without visual regressions across the latest Chrome, Firefox, Safari, and Edge. 2. Lighthouse performance score remains ≥ 90 on the affected pages. 3. Tests pass in GitHub Actions and coverage does not drop. 4. No new ESLint or TypeScript warnings. Drop a short note outlining your most relevant React work and include a link to a recent pull request or code sample that shows how you approach component architecture and state management. I review submissions daily and will invite the strongest profiles to a brief technical chat.
