Hello, I’ll develop a custom e-commerce app for iOS and Android, ensuring fast performance, secure authentication with user profiles, and seamless payment gateway integration. The build will feature a clean, scalable architecture, optimized checkout, and an admin-ready backend for product, order, and user management. Questions: – Which payment gateways should we integrate at launch (Stripe, PayPal, Apple Pay/Google Pay), and in which countries? – Do you have a preferred tech stack (React Native/Flutter native modules) or should I propose one based on your timeline? – What’s included in the MVP beyond auth and payments (catalog, cart, wishlist, orders, push notifications)?

Hello, I have previously built an E-Commerce app, so I have experience with online store platforms. In the app, sellers can add items, and customers can create accounts to browse and search for products. Once customers find the items they need, they can make a selection and place an order directly through the platform. Major Functionality will be: User login & registration. - User can search for products. - Add to cart functionality. - Checkout functionality (Here if a user is not registered the user has to register first to pay). - Delivery option. - Track Order. - See order history and order status as well. - See profile. - Logout. I am a professional iOS & Android Developer for the last past 7 years. In that role, I delivered lots of iPhone & Android apps. I would love the opportunity to collaborate with you on this project. I am very fast, very efficient, and very affordable. Can you please share the detailed requirement if available, based on which I can come up with my understanding, queries, and suggestions?
