I’m building a dedicated Android application that lets users browse, purchase, and instantly access digital products. Think of items such as e-books, audio files, software keys, or any downloadable content that can be delivered straight to the user’s device the moment a transaction is confirmed. What I’m looking for is an Android developer who can take this concept from clean architecture through to launch on Google Play. The core of the job is creating a smooth catalogue and checkout experience optimised for mobile, then handling the secure delivery of the purchased files. Clean code, reliable state management, and attention to UX details (progress indicators, purchase confirmation, download status, error handling) are all important to me because the product is intangible—customers must feel confidence from the first tap to final download. I already have a basic product list in spreadsheet form and brand guidelines ready. You’ll translate those into the app’s data layer, implement the storefront, and wire up the purchase-to-delivery flow. If you have prior experience with licensing, DRM, or managing large media downloads, please highlight it when you respond. Once the APK passes internal testing and meets Google Play requirements, our collaboration is complete, but I’m open to ongoing maintenance on a separate agreement.
