Android Mobile App Development

I need a skilled Android developer to transform my concept into a fully functional, Play-Store-ready application. The project targets the latest Android releases, so solid knowledge of native Android (Kotlin or Java) is essential. I’m open to modern frameworks such as Flutter if you can guarantee a smooth Android-only build.

Scope
• Translate my wireframes and user-flow notes into an intuitive UI that runs smoothly across common screen sizes.
• Build the complete feature set we finalise together; possibilities may include push notifications, secure user sign-in, or even in-app purchases, so prior experience with Firebase, Google Play Billing, or similar services is valuable.
• Integrate any necessary back-end APIs, set up local data caching, and ensure the app remains performant offline.
• Conduct thorough QA on real devices and emulators before submitting the final build to me for review and eventual Play Store release.

Deliverables
1. Clean, well-documented source code in a private Git repository.
2. Compilable APK/AAB plus pro-guard mapping (if used).
3. Brief setup guide so any Android Studio installation can reproduce the build.

When responding, let me know:
• A couple of Android apps you’ve shipped that best match this scale.
• Your preferred toolchain and why it suits this project.
• A rough timeline from kick-off to first test build, including time you allocate for bug-fixing before hand-over.

I look forward to collaborating and bringing this Android-only idea to life.
