Front End Developer – React/Responsive Web | Mobile + Java Backend

Responsible for delivering a fully functional, production-ready frontend for our web platform. This includes: - A responsive user interface built to match approved designs/wireframes, working seamlessly across desktop, tablet, and mobile screen sizes. - The freelancer will develop a reusable component library (buttons, forms, modals, navigation, cards, etc.) using React, ensuring consistency across the platform. - All pages should be tested and functional across major browsers (Chrome, Safari, Firefox, Edge). - The frontend must be properly integrated with our Java-based backend APIs, including correct handling of loading states, errors, and data validation. - This includes setting up routing/navigation across all pages, implementing client-side form validation, and connecting authentication flows (login/signup/logout) where applicable. The final build should be optimized for performance — fast load times, lazy loading where needed, and optimized images/assets. Basic accessibility standards (semantic HTML, keyboard navigation, alt text) should be followed throughout. . - Core UI build — all pages/components matching design - Backend/API integration — data flowing correctly, auth working - QA, optimization, and final handoff — bug fixes, docs, deployment-ready build.
