I’m ready to launch an e-commerce application that runs smoothly on both iOS and Android. The key requirement is rock-solid payment integration so customers can complete purchases in-app with absolute confidence and speed. Here’s the flow I have in mind: users browse the catalog (I’ll supply product data and artwork), add items to their cart, then pay securely using the gateway you wire in. I’m flexible on the underlying stack—whether you prefer Flutter, React Native, Swift + Kotlin, or another proven approach—so long as the final builds pass App Store and Google Play review without a hitch. Deliverables • Fully functional iOS and Android builds • Source code and brief setup documentation • Integrated, tested payment gateway with sandbox and production keys • Basic admin-side instructions for managing products and orders Acceptance criteria • Payments process successfully in both test and live modes • UI follows each platform’s human-interface guidelines • No critical crashes or performance bottlenecks on current OS versions If this scope fits your skill set and timeline, let’s discuss the finer points (gateway selection, deployment plan, and milestone schedule) so we can get the checkout ringing.

Hi, I can build your cross-platform e-commerce app with a fast, secure, and production-ready payment flow for both iOS and Android. I’d recommend Flutter for a smooth UI, faster development, and easier long-term maintenance while ensuring both App Store and Google Play compliance. I can integrate reliable payment gateways such as Stripe, Razorpay, PayPal, or others with full sandbox + live environment support. A few quick questions: =================== Which payment gateway do you prefer? Do you already have a backend/API, or should it be developed as well? Will the app include guest checkout or only logged-in users? Do you need push notifications for orders and promotions? What is your expected launch timeline? I can help take the project from development to store deployment smoothly. Best regards
