Flutter Mobile App & React Website

I’m building a cross-platform solution that pairs a Flutter mobile application with a React-based website.

On the mobile side, I need one clean Flutter codebase that compiles for both iOS and Android. Core functionality includes secure email-and-password authentication; a Firebase setup would be perfect, but any equally reliable approach works for me. Smooth navigation, responsive UI, and maintainable state management are priorities.

The web component should be written in React. It will consume the same backend endpoints as the app, so experience orchestrating a shared API layer between Flutter and React will be invaluable. I expect production-ready code, clear component structure, and an eye for performance.

Deliverables
• Flutter source ready to ship on iOS & Android
• React source ready for a production build
• Concise setup instructions so I can run everything locally

Please tell me about similar projects you’ve handled and the timeframe you foresee. I’m ready to get started as soon as we align on the plan.
