The Buyer-side APIs for our ONDC deployment are already live; now I need a modern, fully responsive web interface that turns those endpoints into a polished e-commerce experience. You will consume the Buyer Protocol and Buyer CRUD APIs I provide and deliver a single-page front end that covers every core flow: • Catalog search that leverages the data exactly as the APIs expose it, supporting filters, sorting and predictive behaviour where the data allows. • Seamless cart, checkout, init, confirm, cancel, refund and rating flows, always honouring ONDC status transitions. • Order tracking and issue management pages tied to the corresponding endpoints. • AI layer: an on-page chatbot for customer support plus a recommendations module that learns from user activity; the voice feature can stay optional for later. The look and feel must stay clean and contemporary—think modern typography, spacious layouts, subtle animations and mobile-first breakpoints. I will share Postman collections, Swagger docs and a private repo as soon as we start; your branch should include clear commits, reusable React (or comparable) components, TypeScript where practical, SCSS or Tailwind for styling and unit tests for critical logic. Completion means: 1. The app runs locally with one command, builds cleanly for production and deploys error-free to our test server. 2. All API calls conform to ONDC schemas; validation errors surface gracefully in the UI. 3. Chatbot replies and recommendation cards pull from the AI service keys I supply and degrade gracefully if the service is unavailable. 4. Lighthouse mobile score ≥ 90 and no console warnings. If you have shipped ONDC-compliant buyers before and can work within the stated cost and timeline, let’s get started—repository access is ready for you.

Hey, I will build a modern, responsive single page frontend that transforms your ONDC Buyer APIs into a smooth, production ready e commerce experience covering catalog, cart, checkout, order lifecycle, and support flows. The app will be developed using React with TypeScript, structured into reusable components with clean state management and API abstraction layers to strictly follow ONDC schemas. I will implement search with filtering and sorting, full cart to checkout flows including init, confirm, cancel, refund, and rating, along with order tracking and issue management screens. The UI will follow a clean, mobile first design with optimized performance, smooth transitions, and Lighthouse scores above 90. For the AI layer, I will integrate a chatbot and recommendation module that connects to your provided services, ensuring graceful fallbacks if unavailable. The project will be fully testable, Docker friendly if needed, and run locally with a single command, with clean builds and structured commits for easy collaboration. Questions: Do you have a preferred state management approach such as Redux or should I choose the best fit? Will authentication and user sessions be handled via your APIs or need frontend handling as well? Looking forward to potentially working together.

The plan: React + TanStack Query with a typed client wrapping each Buyer endpoint pair. Every cart and checkout action dispatches the intent and waits on the on_* callback before advancing state, because the protocol doesn't give you a synchronous confirm. Hard state machine for status transitions so the UI never surfaces a state ONDC disallows. Optimistic updates only where the protocol actually permits them, not as a workaround for the two-step flow. The init/confirm sequence gets designed first and the cart UI gets built around it. That way the checkout flow reflects what ONDC actually does, not what a typical e-commerce SPA assumes. M1: Typed client + catalog search + cart, INR 2375, 4d. M2: Checkout (init/confirm), INR 2375, 4d. M3: Cancel/refund/tracking, INR 2375, 3d. M4: Polish + handoff, INR 2375, 3d. What does your on_* callback delivery look like right now - polling endpoint, webhook, or SSE? That determines how I wire up the query layer.
