I need a clean, lightweight Android application that lets my customers browse RAM, SD cards, Pendrives, and any other items I add in the future. The core screens should load fast on even modest phones and tablets, keeping navigation intuitive so first-time users find what they need in seconds. Everyone can explore the full product catalog, read specs, see images, and place orders directly from the app. A simple guest checkout is fine, but when users decide to track an order, save a wish list, or unlock exclusive discounts, they must create an account or sign in. That way only the value-added areas sit behind authentication, while the rest of the experience stays friction-free. A small customer-review section under each product will help buyers share feedback. I’m not looking for anything bloated—just star ratings with an optional short comment. To keep maintenance straightforward, I prefer standard Android Studio tooling. Kotlin is ideal, but Java is acceptable if you already have solid templates you can adapt quickly. Local caching for images and a sensible API layer will ensure the app stays snappy on slow connections; feel free to recommend Firebase, REST, or another lightweight backend approach if it speeds development. Deliverables • Signed APK + source code that builds in Android Studio • Basic README covering setup, build steps, and how to point the code at my product feed / backend • A short hand-off call or video walkthrough so I can update the catalog myself If everything runs smoothly I plan to expand the feature set, so clean, well-commented code is important for future iterations.
