Hello, I will build your mobile application with the core user flows, backend API, and deployment to both app stores. The app will handle authentication, data sync, and push notifications. I will architect the app with offline-first capability where critical data is cached locally so users are not blocked when connectivity drops. Questions: 1) Do you have an existing backend/API, or does that need to be built as well? 2) Are there any specific third-party integrations required? 3) Do you have the Apple Developer and Google Play accounts ready? Ready to start whenever you are. Kamran

Hi, This looks like a checkout-focused Android build where performance and payment reliability matter more than feature volume. I can develop the app in Kotlin using MVVM architecture with Retrofit integration, ensuring smooth cart updates, promo handling, and a fast, low-friction checkout flow connected to your existing APIs. Stripe integration with secure tokenised payments, order confirmation flow, and Firebase Crashlytics monitoring will be implemented to meet Play Store and sandbox certification requirements from the first release. We can start immediately — I will ensure clear, daily communication and fast turnaround. You’ll always know the exact progress. Happy to discuss timeline and preferred libraries before development begins.

@sagarlohni

Hello, I can build your Android e-commerce core in Kotlin with a clean MVVM architecture, focused entirely on a frictionless cart and secure checkout experience. Since your backend API is ready, I’ll structure the app for performance and scalability: • MVVM + Repository pattern • Retrofit for API integration • Real-time cart updates (quantity, promo codes, tax, totals) • Stripe (mandatory) with secure tokenised flow • PayPal integration (optional but scalable-ready) • Order confirmation + receipt trigger (API/email/push) • Firebase Crashlytics for monitoring • Play Store compliant signed release build Security & stability will be prioritized to pass: • 50-item checkout stress test • Stripe sandbox certification • Play Console pre-launch checks Deliverables: • Internal testing APK + Play-ready bundle • Complete Git source code (clean, documented) • Setup/hand-off guide with staging/production switching I build scalable foundations, so adding iOS or user accounts later will be seamless. Let’s review your API structure and payment requirements so I can outline milestones clearly. — Sagar

@Syedh1998

Hello, building a frictionless checkout flow is exactly where Android apps succeed or fail. I’ve developed Kotlin-based e-commerce apps focused on fast cart interactions, secure Stripe payments, and stable checkout flows that pass Play Store pre-launch testing without crashes. For your project, I would implement a clean MVVM structure using Kotlin, Retrofit for API communication, and lifecycle-aware components so cart updates, quantity edits, promo codes, and totals refresh instantly without UI lag. Stripe integration will follow PCI-compliant tokenized payments, with optional PayPal support added in a modular payment layer so additional gateways can be integrated later. The checkout journey will be optimized to minimize taps, leading to a clear order confirmation screen with push or email receipt triggers. Firebase Crashlytics will monitor runtime stability, helping ensure the 50-item checkout stress test passes with zero crashes and smooth performance. You’ll receive a signed APK for internal testing, Play-Store-ready build, full Git source code with clean documentation, and a short setup guide explaining build steps and switching between staging and production APIs. If helpful, I can also outline the checkout architecture and timeline before we begin the first milestone. Syed
