E-Commerce Cart & Checkout UI

I’m building an e-commerce website and I need an extra pair of hands to finalise the shopping-cart and checkout flow on the frontend. The catalogue pages and backend endpoints are already in place, so the focus is purely on the user interface: adding items to the cart, updating quantities, showing real-time totals, then guiding the shopper through address, shipping, payment and confirmation screens.

You may work in plain JavaScript, React, Vue or another modern framework—whichever lets you move fastest while keeping the final bundle lean and mobile-responsive. Stripe elements are ready on the backend, so the payment step only needs the correct hooks and error states on the UI side.

Deliverables
• Responsive cart page that consumes my existing product and pricing APIs
• Multi-step checkout component with form validation and graceful error handling
• Sub-total, tax, discount and shipping calculations rendered live
• Polished styling that matches our current brand tokens (Figma file supplied)
• Build/run instructions and a brief hand-off walkthrough

I’ll provide the API docs, staging keys and a short Loom video of the current flow. Once the components slot in cleanly and pass my Cypress smoke tests, the job is done.
