You have a complete React frontend ready to go—now it needs to come alive by connecting to your backend APIs. The scope covers authentication flows, token management, error handling, loading states, and state management—all while keeping your existing UI untouched and ensuring clean, maintainable code. I will integrate your documented REST APIs into your functional React components, implementing secure login/logout with token storage and refresh handling. Using Axios for API calls and React Context for state management, I'll add proper loading indicators, consistent error handling, and performance optimizations where needed—delivering a fully functional application that communicates seamlessly with your backend. I have extensive experience with React API integrations, including several e-commerce dashboards and SaaS applications where I connected complex backend systems to polished UIs. To provide an accurate timeline, could you share approximately how many API endpoints need integration and whether authentication is JWT-based or uses another approach?

Integrating a robust REST API with a pre-built React UI requires a precise approach to state management and error handling to ensure the frontend remains responsive and reliable. Having the UI already developed means we can focus entirely on the technical implementation of data flow, which is often where performance bottlenecks emerge. Based on the scope of wiring your complete UI to a backend service, my suggested budget is 10900 INR. This covers a systematic delivery plan for integrating core CRUD operations, implementing consistent loading and error states, and ensuring the API responses are correctly mapped to your existing components. A concrete milestone would be having a fully interactive prototype with a connected endpoint for your primary data entity. To provide the most accurate solution, could you describe the current structure of your React state management? Knowing whether you use Context, Redux, or another library will help tailor the integration strategy for maintainability.
