I need like Coach Surfing web + mobile app. [login to view URL] I have an existing Flutter mobile application that already communicates with a Node.js backend. I now want to push it further: tidy up the current codebase, add several new screens, tighten the API layer on the server, and introduce a small yet meaningful AI feature (think personalised recommendations or basic natural-language queries—exact scope to be agreed together). Here is what I need from you: • Flutter work – polish the present UI, wire in the new screens I will supply as Figma frames, and be sure state management stays clean and predictable. • Node.js work – extend the current Express API, connect the new endpoints to MongoDB, and add role-based authentication so the app can distinguish between guest and premium users. • AI layer – build (or integrate) a lightweight model or third-party service, expose it through the Node.js API, and demonstrate the end-to-end flow inside the Flutter app. Deliverables will be the updated Flutter project, the enhanced Node.js repo, clear environment setup notes, and a concise README that explains how to run the AI component locally. All code should be well-commented, push-ready on Git, and built with maintainability in mind. Once everything compiles and the new AI feature returns the expected output in the mobile app, we’ll call the milestone complete.

Hi there, As you already have a Flutter application and Node.js backend in place, I can quickly jump into the existing codebase, improve the UI, add the new Figma-based screens, extend the APIs, and implement role-based authentication without rebuilding anything from scratch. Once the Flutter and backend enhancements are completed, I will work on the AI layer and integrate the agreed AI functionality through the Node.js API, ensuring the complete flow works seamlessly inside the mobile application. I would request to connect once so we can review the current architecture, discuss the AI use case in detail, and finalize the implementation approach before getting started. Thanks, Rahul A.

Hello, I have gone through your requirement for upgrading your existing Couchsurfing-style Flutter app with Node.js backend enhancements and an AI-based recommendation layer. I understand you want both cleanup of the current codebase and addition of new features while keeping the architecture scalable and maintainable. I can take care of the full-stack improvements including refining your Flutter UI, integrating new Figma-based screens, and ensuring state management remains clean and modular. On the backend side, I will extend your existing Express APIs, optimize MongoDB integration, and implement secure role-based authentication for guest and premium users. For the AI component, I will integrate a lightweight solution (OpenAI API or similar model-based service depending on your preference) and expose it through your Node.js layer, ensuring seamless communication with the Flutter frontend for real-time personalized recommendations or query-based responses. Before starting, I would like to confirm: do you prefer using a third-party AI API (faster implementation) or a custom lightweight model setup on your server for more control? Once confirmed, I can immediately begin structuring the backend updates, cleaning the Flutter architecture, and integrating the AI flow end-to-end. I will also provide clean Git commits, setup documentation, and a clear README so your team can easily maintain and extend the system. Looking forward to working with you on this upgrade.

Hello, hope to reach my proposal. Your project is very interesting, especially with the vision of evolving an existing Flutter application into a platform similar to Couchsurfing with enhanced user experiences and AI-powered features. I have experience working with **Flutter, Node.js, Express, MongoDB, REST APIs, authentication systems, and AI integrations**. I can help refactor and organize the existing codebase, implement the new Figma-based screens, improve state management, and ensure the application remains scalable and maintainable. On the backend, I can extend the existing Node.js API, create new endpoints, optimize database interactions, and implement secure role-based authentication for guest and premium users. For the AI component, I recommend integrating a lightweight recommendation engine that can suggest hosts, travelers, locations, or activities based on user preferences and behavior. This can later be expanded into natural-language search and smart matching capabilities. The deliverables will include the updated Flutter application, enhanced Node.js backend, AI integration, Git-ready source code, environment setup documentation, and a clear README for deployment and maintenance.
