I’m launching a mobile storefront dedicated to clothing and accessories and I need a full-featured Android application built from scratch. The app will sell physical products only, so everything—from the product catalogue to checkout—must feel seamless on a phone. Core functions I have in mind: • Secure payment gateway integration that can handle major cards and wallets without redirecting the shopper. • Robust search and layered filters so users can quickly narrow items by size, color, price, and brand. • A user-generated reviews & rating system tied to verified purchases. • Real-time logistics updates once an order is placed, showing shipment status inside the app. • A multi-seller setup that lets several vendors maintain their own inventory while I control everything from a single admin console. Please build the app natively for Android (Android Studio using Kotlin or Java is fine) and package it with clean, well-commented source code. An admin panel or at least clearly documented APIs for product, order, and vendor management are part of the expected hand-off. Final deliverables include the complete source, a signed APK/AAB ready for Play Store submission, and a brief deployment guide so I can replicate the build and push updates myself. If you have questions about specific payment gateways or logistics APIs, let me know—otherwise feel free to suggest proven solutions you’ve used before. I’m ready to get started as soon as we agree on the tech stack and timeline.
