React.js SaaS E-commerce Development

My e-commerce SaaS platform already has the core concept in place and a lightweight MVP wired up in React.js. The next milestone is a polished, production-ready front-end that can scale gracefully as new merchants onboard.

What’s waiting on your desk: extending and refining the existing React codebase, building out reusable components for product listings, shopping-cart flows, and user dashboards, then wiring them to the current REST/GraphQL APIs. A keen eye for responsive design, accessibility, and performance matters just as much as clean architecture.

You’ll be working in a GitHub-based workflow, shipping iterative pull requests, writing concise unit tests with Jest and React Testing Library, and documenting the component library so future contributors can jump straight in.

Deliverables
• Modular, well-documented React components covering the catalogue, cart, checkout, and account areas
• Responsive layouts that pass Lighthouse and Axe accessibility checks
• Integration hooks and error handling for all existing API endpoints
• A basic but solid test suite (Jest + RTL) with at least 80 % line coverage
• Build and deployment instructions that work on a fresh clone

Acceptance Criteria
• All pages render without console errors or warnings
• Core user flows—browse, add to cart, checkout—complete successfully on desktop and mobile breakpoints
• Tests run green in CI and coverage threshold is met
• Code reviews show adherence to the project’s ESLint/Prettier rules

If React hooks, Context/Redux patterns, and component-level performance tuning are second nature to you, this collaboration should feel straightforward and rewarding. Looking forward to seeing what you can bring to this platform’s next release.
