I am launching a fresh Android-only shopping application and need a developer who can take the idea from wireframe to a polished APK ready for the Play Store. The core goal is classic e-commerce: browsing products, adding items to a cart, and completing secure checkout, all wrapped in a clean, modern Material-inspired UI. Here’s what I have in mind: • Native Android development—Kotlin preferred, Java acceptable if you can justify it. • Smooth product catalogue with search and category filters. • Cart, wish-list, and secure payment gateway integration (Stripe or Razorpay are fine, open to suggestions). • User registration/login via email, Google, or Facebook. • Basic order-tracking screen and push notifications through Firebase Cloud Messaging. • A lightweight admin panel or Firebase console setup so I can add/edit products without touching code. Acceptance criteria: 1. App installs and runs on Android 8.0+ without crashes. 2. Checkout flow processes test transactions end-to-end. 3. All major screens pass a quick usability review on mid-range devices. 4. Clean, commented source code delivered via Git. If you’ve shipped an Android shop app before and can show a couple of live links or APKs, I’d love to see them and discuss timelines.
