Android App UX Enhancement

I need a skilled Android developer to transform my concept into a polished, user-centric mobile app. The single, driving goal is to improve user experience, so every design and technical choice must put clarity, speed, and intuitive interaction first.

What I’m looking for
• Turn my rough feature list into wireframes and a clean Material-inspired interface.
• Build the app natively for Android (Kotlin or Java) with responsive layouts that work smoothly across multiple screen sizes.
• Implement straightforward onboarding, clear navigation patterns, and accessible UI components.
• Optimise performance and load times so the app feels fast on both newer and older devices.
• Share iterative APK builds, collect feedback, and refine the experience until it feels effortless.

Deliverables
• Fully functional Android app (APK plus source code).
• UI/UX assets—wireframes and high-fidelity screens.
• Light setup and build documentation so the project is easy to maintain.

Clean, well-commented code and open communication are important to me. If you have past work that shows a strong focus on user experience, please include it when you respond.
