I need a developer who can turn my e-commerce idea into a fully functional Android app. The core features I have in mind include: • Product catalog with search and category filters • Secure user registration, login, and profile management • Shopping cart and checkout flow that supports major payment gateways • Order history and basic push notifications for status updates • Simple admin interface or API hooks so I can add, edit, or remove products without rebuilding the app Clean, maintainable code written in Kotlin or Java is preferred, and the final build must be ready for submission to Google Play. If you have experience integrating payment APIs, optimizing for varied screen sizes, and following Google’s material design guidelines, you’ll be a great fit. Please share a brief outline of your approach, any relevant store links to past Android e-commerce apps you’ve shipped, and the estimated timeframe for an initial MVP.
