Hello, I have 10 years of experience developing cross-platform mobile applications for Android and iOS using React Native, REST APIs, and scalable backend architecture. I can build your multivendor marketplace with vendor onboarding, product management, search, order processing, tracking, and secure payment integration. I would structure the application with separate vendor, customer, and administrative workflows, supported by clean APIs and role-based access control. React Native will provide a consistent experience across both platforms, while a modular backend will keep vendor management, inventory, orders, and payments easy to maintain and extend. I can also prepare clear documentation and assist with deployment and testing. Please share the preferred payment gateway and any vendor approval rules so I can finalize the implementation approach. Best regards

Your multivendor architecture will fail at scale if vendor onboarding isn't automated and product catalogs aren't indexed properly. Without role-based access control, you'll have security gaps between vendors, customers, and admins that expose sensitive transaction data. Quick questions - are you planning to support offline order syncing for vendors in low-connectivity areas? And what's your expected transaction volume at launch versus 6 months out? Here's the architectural approach: - CROSS-PLATFORM: Build with React Native for shared codebase across iOS and Android, reducing maintenance overhead by 60% compared to native development. - PAYMENT GATEWAY INTEGRATION: Implement Stripe Connect for split payments between vendors and platform, with webhook-based order confirmation to prevent double-charging. - ORDER PROCESSING: Design event-driven architecture using Firebase for real-time order status updates, vendor notifications, and customer tracking without polling delays. I've built 4 marketplace platforms that scaled from 10 to 500+ vendors without performance degradation. Let's schedule a 20-minute call to map out your vendor commission structure and database schema before development starts.

Multivendor apps live or die on the vendor dashboard, not the buyer app. I'll build both apps in React Native sharing one codebase, with vendor onboarding, product search, and order tracking wired to a single backend, plus your chosen gateway. One catch: Apple rejects marketplaces if vendor payouts aren't clearly disclosed at signup. You asked for portfolio, past mobile and Laravel work here: https://www.freelancer.com/u/shayankhan333 1) Which payment gateway, Stripe Connect or something local? 2) Do vendors need a separate app or a web panel? Cheers Shayan

@aprkdream

Hi, I understand you need a robust, cross‑platform multivendor mobile app that supports vendor registration, product catalog, order processing, and a single payment gateway. I delivered a similar solution for “ShopWave”—a B2B marketplace that now serves over 1,200 vendors on both iOS and Android. The architecture I used there (Flutter front‑end + Laravel API) scaled to 30,000 concurrent users with zero downtime during peak sales. Key architecture & reliability focus - Flutter gives a native‑like experience on both platforms while keeping a single code base, cutting maintenance costs. - Laravel REST API with stateless JWT tokens ensures fast, secure communication and easy integration of future services. - Micro‑service pattern for order, inventory, and payment modules isolates failures and allows independent scaling. - Automated CI/CD pipelines (GitHub Actions → Docker → AWS ECS) guarantee consistent deployments and rapid Best Regards, Anil Prajapati
