Hi, I want to clearly explain my project so you can understand the full scope and suggest the best technical approach. I am planning to build a **scalable social-commerce platform** (Instagram + Marketplace + Services + Delivery system). ### Core Concept The platform will have: * Sellers (who create shops and list products/services) * Buyers (who are also creators like Instagram users) * Admin (multi-level control system) --- ### User Roles **1. Seller** * Must complete KYC before creating a shop (GSTIN or other business proof required) * Can create one or multiple shops * Can list products or services (grocery, fish, mango, doctor, salon, etc.) * Manage orders, pricing, inventory, and appointments * Cannot directly chat with buyers **2. Buyer / Creator** * Instagram-style profile (posts, reels, stories, followers) * Can discover products/services via feed * Can purchase products * Can book appointments (doctor, salon, etc.) * Messaging only between buyer-to-buyer (no seller chat) **3. Admin (3 Levels)** * Owner (full control) * CEO (high-level control) * Managers (limited permissions) Admin should control: * KYC approval * shop approval * commissions and offers * banning users * feedback/moderation * analytics and reports * delivery operations * platform settings --- ### Core Features * Shop system with unique shop IDs * Product + Service listings * Instagram-style feed (products should also appear in feed) * Viral/engagement-based ranking algorithm * Order system with full data tracking * Appointment booking system * GST invoice generation after purchase * Analytics tracking (Power BI–like data collection) --- ### Delivery System Orders should be routed based on type: * Local/city → delivery partners (like Swiggy/Blinkit) * Long distance → courier system --- ### App Architecture (Very Important) I want this to be built as a **modular system**: 1. Main App * Buyer + Creator + Seller features 2. Admin App (separate panel) * Role-based access (Owner, CEO, Manager) 3. Delivery Partner App (future-ready) * For local delivery agents and dispatch management All apps should: * use the same backend * use same database * use API-based architecture * have proper role-based access control --- ### Technical Expectations * Clean and scalable architecture (prefer MERN / modern stack) * Strong database design (clear relationships between users, shops, products, orders, etc.) * Modular backend (separate services for commerce, social, delivery, admin) * Secure authentication system * API-first design (for future mobile apps) * Analytics/event tracking from start --- ### Future Scope (Important to consider now) * Creator affiliate system (earn from promoting products) * Wallet & payout system * AI-based feed/recommendation * Advanced analytics dashboards * Multi-city scaling --- ### What I Need From You * Suggest best tech stack and architecture * Break project into phases (MVP → scale) * Estimate time and cost * Suggest improvements if needed This is a long-term scalable project, so I want to build it in a structured and future-ready way, not just a basic website. Let me know your approach.
