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.

Greetings, I see that you're looking to enhance your existing Flutter mobile app and Node.js backend, along with adding an AI feature for personalized recommendations. My approach would involve first refining the current Flutter UI, ensuring it remains user-friendly while integrating the new screens you provide. I would also focus on maintaining clean state management throughout. On the Node.js side, I'd enhance the Express API to include the new endpoints and set up role-based authentication to separate guest and premium users effectively. For the AI feature, I can either build a lightweight model or integrate a third-party service to ensure seamless functionality through the API. With attention to detail and a focus on maintainability, I will ensure all code is well-commented and ready for future development. Best regards, Saba Ehsan

Hi, I reviewed your Coach Surfing enhancement requirements and understand that you already have a Flutter mobile application with a Node.js backend and need an experienced developer to extend and stabilize the platform. UNDERSTANDING YOUR REQUIREMENTS • Polish the existing Flutter UI, implement new Figma-based screens, and improve state management. • Extend the Node.js/Express backend, add MongoDB integrations, new APIs, and role-based access for premium users. • Integrate an AI layer for personalized recommendations and natural-language search/query capabilities. CHALLENGES & SOLUTIONS Challenge: Growing Flutter apps often become difficult to maintain due to inconsistent state handling. Solution: Refactor key modules, improve state management, and create reusable UI components. Challenge: Expanding APIs can introduce performance and maintenance issues. Solution: Implement clean service architecture, optimized MongoDB queries, and secure RBAC. SKILLS & EXPERIENCE I have 13+ years of experience building SaaS, mobile, and enterprise applications using Flutter, Node.js, MongoDB, Angular, React, Firebase, and Azure. I have delivered scalable products including Adopals, Solidcare, Lexis Convey, and Airvolution. QUESTIONS 1. Which state management solution is currently used in Flutter? 2. Is an AI provider already selected? I focus on clean, maintainable code and long-term scalability, not just feature delivery.

⭐ Hi there ! Your Couchsurfing-style app needs clean Flutter updates, stronger Node.js APIs, live Google Map features, and a small AI layer that works end-to-end. At Globant, I worked on Flutter + Node.js apps where Figma screens, MongoDB APIs, user roles, and location-based features had to stay stable together. One travel-style mobile app improved screen load speed by 42% after cleaning the API and state management flow. I can polish the Flutter UI, add your new screens, improve Express endpoints, connect MongoDB, add guest/premium authentication, and integrate AI recommendations through the backend. I’ll keep the code push-ready with clear setup notes and README. Hourly rate: $8/hr. Do you already have the AI feature defined, or should I suggest the best recommendation flow for your app?
