Android Mobile App Development Needed

I need a skilled Android developer to turn my concept into a fully functional mobile app. The project is strictly for the Android platform—no web or desktop versions are required for now. At this stage the core idea is defined, but I’m still finalising the feature set, so I’ll rely on your expertise to translate high-level requirements into an intuitive UI, solid architecture, and clean code. You should be comfortable working in Android Studio with Kotlin or Java, integrating standard Android SDK components, and advising on best practices for performance, security, and Play Store compliance. I’ll provide a high-level workflow and rough wireframes; you’ll refine them, implement the app, and keep me in the loop through frequent builds. Deliverables • Release-ready APK suitable for Google Play submission • Complete, well-commented source code • Brief setup & deployment notes Acceptance Criteria • App installs and runs without crashes on the current Android OS and two major versions back • UI matches agreed mock-ups within reasonable variance • No critical lint or security warnings in the final build If you’re confident you can guide the project from idea to store-ready product, I’d love to hear how you would approach the build and an estimated timeline.
