I need a mobile app created for the Android platform. The project starts with refining the concept together and moves through design, coding and final deployment to Google Play, so you’ll be handling the full development life-cycle while keeping me in the loop at each milestone. Feel free to recommend the best tech stack—whether native Kotlin, Flutter, Firebase back end, or another solution—so long as the code remains clean, well-documented and easy to maintain. Key deliverables: • Interactive wireframes or prototype for my approval • Production-ready Android App Bundle (AAB) that meets current Play Store requirements • Complete, well-commented source code and build instructions • Short hand-off session to walk me through deployment and future updates If you have shipped Android apps before, share links, a brief overview of your approach and an estimated timeline so we can get started.
