I am gearing up to launch a brand-new e-commerce experience on Android and need a seasoned full-stack developer who can take the concept from wireframes to a polished, store-ready APK. Here’s the core vision: an intuitive shopping app where customers can browse a well-structured product catalog and create their own accounts through a secure signup/login flow. Smooth navigation, fast loading times, and clean UI/UX patterns are non-negotiable because I want users to feel the same confidence they do on any leading online store. Scope of work • Architecture & tech stack: I’m open to your preferred tools—Kotlin or Java on Android Studio for the front end, and a robust back-end stack (Node.js, Django, Firebase, or similar) that scales effortlessly. • Core features for Phase 1: – User login & signup (email, Google, or phone). – Dynamic product catalog with category filters, search, and detailed product pages. • Admin panel: Basic dashboard to upload/edit products, images, prices, and inventory status. • APIs & database: Design secure, well-documented REST/GraphQL endpoints, integrate realtime updates where it makes sense, and follow best practices for data storage. • Testing & publishing: End-to-end testing on multiple screen sizes, then deployment to Google Play (including listing assets if you can assist). Acceptance criteria 1. New users can register and log in without crashes or unexpected errors. 2. Catalog loads quickly, showing accurate titles, prices, and images pulled from the back end. 3. Admin panel updates reflect in the app within seconds/minutes (based on chosen architecture). 4. Codebase is clean, documented, and handed over in a private Git repository, accompanied by build instructions. Phase 2 (optional, not part of the initial deliverable) will add payment gateway integration and advanced order tracking. If this launch goes smoothly, I’m eager to keep collaborating on that expansion. Tell me a bit about similar Android e-commerce apps you’ve built, the stack you’d recommend, and how long you’d need for this first release. I’m ready to get started as soon as we align on a timeline and milestones.
