Premium Flutter Marketplace App Frontend

**Title: Experienced Flutter Frontend UI/UX Developer Needed – iOS & Android Marketplace App**

Hello,

I am looking for an experienced Flutter developer with strong UI/UX design skills to design and develop the complete frontend of **CHERCHEPLUS**, a mobile marketplace application for individual and professional sellers.

**PROJECT OBJECTIVE**

Create a modern, premium, professional mobile application with smooth navigation, fully interactive screens, and a clean architecture ready for future backend integration.

**SCOPE OF WORK**

- Design and development of all Flutter screens.
- Modern, consistent and professional UI/UX.
- Home, search, categories and subcategories.
- Product details, favorites and user profiles.
- Registration, login and account settings.
- Product listing creation and management.
- Buyer/seller price negotiation interface.
- Messaging unlocked after payment.
- Checkout and secure payment interface.
- Buyer protection information screens.
- Order and shipping tracking.
- Dispute and claim management.
- Personal profile, wallet, purchases and sales.
- Notifications.
- Complete navigation, animations and functional interactions.

**BACKEND COMPATIBILITY**

This project is strictly for Flutter frontend development.

Backend services, PostgreSQL database, MangoPay payments and Colissimo shipping integration will be handled separately.

The frontend must be designed for future integration with REST APIs and a Node.js/NestJS backend architecture.

UI components, data models and API services must be properly separated.

All features must be demonstrable using mock data, including loading, success and error states.

API integration points must be clearly documented. Required data contracts will be shared with the selected developer.

No backend development or real payment processing is required.

**TECHNICAL REQUIREMENTS**

- Flutter/Dart only.
- iOS and Android compatibility.
- Responsive interfaces.
- Clean, modular, commented and documented code.
- Functional navigation and interactive buttons.
- Testing of key user interactions.
- Delivery of Figma design files and graphic assets.
- Complete source code delivered to the client's private GitHub repository.
- Regular commits and technical documentation.
- Full ownership and intellectual property rights transferred to the client.

**SELECTION AND DELIVERY**

An initial personal profile screen will be requested as a first agreed project milestone.

I am looking for a professional capable of delivering a complete, visually polished, stable Flutter frontend that can be easily integrated with an independent backend.

Please provide your Flutter portfolio, relevant references, quotation and estimated delivery timeline.

Thank you.
