I’m looking for an Android developer to create a business-grade e-commerce app for my company. The app’s main purpose is to let customers browse our catalogue and complete purchases directly on their phones. What I need in this first build • Product catalogue: category browsing, search, and item pages with images, pricing, and descriptions. • Secure payment gateway integration: support for cards and UPI, with order confirmation and receipt generation. • Modern, lightweight UI following Material Design guidelines, tested on mid-range devices running Android 8+. Tech expectations • Latest stable Android SDK, written in Kotlin or Java. • Clean, modular architecture (MVVM or similar) so we can add user reviews and loyalty features later. • Use well-maintained libraries (e.g., Retrofit, Room, Jetpack components) and follow Google Play policies. Deliverables 1. Functional APK and Play-Store-ready AAB. 2. Complete, well-commented source code in our private Git repo. 3. Brief setup documentation plus a handover walkthrough (video or live call). 4. One round of post-test refinements. Schedule I’d like a working prototype in about three weeks and final delivery two weeks after that. When you reply, please mention: • Your preferred payment gateway libraries. • Links to similar apps you’ve built. • A concise timeline and any questions you have about the scope. I’m ready to move quickly once I find the right developer.
