I’m ready to move forward with a full-scale mobile app creation project focused solely on the Android platform. The core idea is already sketched out, but I’m leaving room for your technical insight on architecture, feature flow, and interface polish. Here’s what I need from you: • End-to-end Android development, preferably in Kotlin with Android Studio. • Clean, well-commented source code pushed to a private Git repository. • A testable APK throughout the sprint cycle and a release-ready build for Google Play when we’re done. • Basic UI/UX aligned with current Material Design guidelines—nothing flashy, just intuitive and responsive. • Guidance on best practices for device compatibility, performance optimisation, and secure data handling. If you can own the full development cycle—planning, coding, iterative testing, and final deployment—I’d love to hear how you’d approach it and a realistic timeline for delivery.
