@Srashtasoft

Hi there, I have read your project requirement. You need a cross-platform mobile shopping app (iOS & Android) with catalog browsing, cart, secure checkout, search, push notifications, and account management, integrated with your existing inventory APIs. We can build this using Flutter or React Native (based on your preference), ensuring smooth performance, clean UI, and seamless API integration. The app will include product listing, search/filter, cart & checkout with payment gateways, push notifications for order updates, and user account management. We will also ensure compliance with App Store and Google Play guidelines, along with proper testing and deployment support. A few questions to clarify: ===================== Which payment gateways do you want to integrate (Stripe, Razorpay, PayPal, etc.)? Do you need guest checkout or only logged-in users? Are APIs fully ready or require minor adjustments? Do you want analytics integration (Firebase, Mixpanel)? Best Regards, Srashtasoft Team

@royalwebraisers

Hi, As per my understanding: you need a cross-platform eCommerce app with catalog, cart, secure checkout, search, notifications, and API integration, ready for App Store and Play Store. Approach: * UI/UX design + reusable components * API integration for catalog, cart, orders * Payment gateway + push notifications * Testing, store compliance, deployment Queries: * Preferred stack: Flutter or React Native? * Which payment gateways? * Inventory API auth type? I will share my portfolio on your first message. I will be looking forward to hearing from you. Kindest Regards

Your existing inventory API will become a bottleneck the moment you hit 500 concurrent users during a flash sale. Most legacy PHP backends aren't built to handle mobile app traffic patterns - you'll see cart timeouts and checkout failures if we don't implement request queuing and offline-first architecture from day one. Before I map out the technical approach, I need clarity on two things. First, what's your current API response time under load - are we talking 200ms or 2 seconds per product fetch? Second, does your payment gateway support tokenization, or will we need to build PCI-compliant card storage? These answers determine whether we need a caching layer and how we handle payment failures during network drops. Here's the architectural approach: - REACT NATIVE + TYPESCRIPT: Build reusable components with strict prop validation to prevent runtime crashes that trigger app store rejections. I'll implement Redux Toolkit for state management so cart data persists even if the app crashes mid-checkout. - STRIPE + PAYPAL INTEGRATION: Set up 3D Secure authentication flows and webhook listeners to handle delayed payment confirmations. I've seen apps get rejected for missing SCA compliance - we'll avoid that. - PUSH NOTIFICATIONS: Configure Firebase Cloud Messaging with deep linking so "order shipped" notifications open directly to tracking screens, not just the home page. - OFFLINE MODE: Cache product catalogs locally using AsyncStorage and queue failed API calls with retry logic. Your customers won't lose their cart if they walk into a dead zone. - APP STORE COMPLIANCE: I've launched 18 apps through both review processes. I'll handle the privacy manifest requirements Apple added last year and ensure your payment flows meet Google's new transaction disclosure rules. I've built similar e-commerce apps for 4 clients that now process $2M+ monthly through mobile. I don't start coding until we've stress-tested your API endpoints and confirmed your CSV import won't corrupt product variants. Let's schedule a 20-minute call to walk through your backend architecture before I commit to a timeline.

@aadips

A full-featured shopping app covering catalog browse, cart, secure checkout, push notifications, and account management with your existing inventory API is a well-scoped React Native build we can deliver cleanly. Our approach: React Native (our recommendation over Flutter for your use case given the existing API integration) with a clean component-based UI using your brand assets. We will wire the front end to your inventory API per your documentation, implement cart and checkout with popular payment gateways (Razorpay or Stripe depending on your preference), add Firebase push notifications for order updates, and handle product search with basic filtering. CSV product data import will be handled during setup. The app will be tested for both App Store and Google Play submission requirements before handover, including all metadata, screenshots, and compliance checks. Deliverables: full source code, build scripts, and a deploy guide as specified. We have shipped 30+ mobile apps across iOS and Android. 4.9 stars from 118 clients, 97% on-budget delivery. Which payment gateway do you prefer -- Razorpay, Stripe, or another option? And does your existing API have authentication already set up?
