We are a tech agency based looking for a highly skilled Full-Stack Development Team or a Senior Full-Stack Developer to build a complex B2B e-commerce platform for mobile accessories. This is an enterprise-level project. It requires deep expertise in Flutter (UI/UX), WooCommerce Custom REST APIs, Multi-Warehouse Inventory Logic, AI Integration (xAI Grok), and Middleware routing (Microsoft Dynamics 365). Project Overview: We are building a "Single Instance" WooCommerce backend that powers a high-performance Flutter mobile app (iOS and Android). The system must handle products tailored to diverse market needs, allowing the same item to be presented with 4 independent variables: Country, Stock Level, Price, and Currency. How to Apply: To prove you have read this entire description and are not an automated bot, please start your proposal with the exact phrase "DHGATE-ORANGE". Please include: Links to 2-3 of your best Flutter e-commerce apps (especially those with dense grids/infinite scrolling). A brief explanation of how you will handle the Multi-Warehouse inventory synchronization. Your estimated timeline and budget for this complete scope. Key Technical Requirements and Scope of Work: 1. Mobile App Frontend (Flutter): UI/UX Standard (DHgate/AliExpress Style): The design must feature a high-energy, AliExpress-style orange palette and Temu-style gamified infinite scrolling. The home page must include dense product grids, "Super Deal" countdowns, and vibrant category icons. Product Detail Page (Amazon Layout): The PDP must mimic the Amazon layout with a rich mix of Video and Images. Crucial: The system must enforce a strict media sequence where the Video plays first to grab attention, followed by the Main Image and Detail Images. Region Selector: A splash screen/popup for users to select their country on the first launch. 2. Backend Core (WooCommerce + Custom API): Data Isolation: The backend architecture must ensure that price updates or stock changes in one country (e.g., Peru) strictly do not affect the data presentation in another country (e.g., Chile). Multi-Tier Inventory System: The system must manage multi-tier inventory: Warehouse A (Central) handles Online Sales, while Warehouses B and C correspond to specific cities for offline sales. If an offline store sells an item, the App must update immediately to prevent overselling. B2B Features: Implement "User Groups" (e.g., Distributor_Region_A) where admins can hide specific low prices from certain groups to prevent cross-region competition. Implement "Quantity-Based Rules" for automatic discounts (e.g., Buy 10 or more units, Get 5% Off). Custom Logistics: The order management module must include custom text fields for Carrier Name and Tracking Number to allow manual input of non-standard logistics (e.g., Bus Lines, Private Air Freight). 3. AI Shopping Assistant (xAI Grok Integration): Implement an "AI Floating Window" (Fully Automated AI, no human entry). Replace the traditional search bar with an "Ask Grok" no-keyboard interaction. The AI must be trained on our product specs to recommend products based on parameters. (We will provide the raw training data; you build and deploy the model). 4. ERP Smart Middleware (Dynamics 365 Routing): You must build a robust Middleware (using Node.js, Python, or n8n) that catches WooCommerce webhooks and intelligently routes the order to the correct Dynamics 365 OData API entity based on the user's region. Failsafe: Must include a retry mechanism to prevent data loss. (Note: Features requiring "1-minute interval API fetching" and "Mandatory Secondary Stock Verification" at checkout are NOT included in this scope).
