I am starting completely from scratch and need a developer who can transform a simple idea into a working native Android application. The only confirmed requirement is a smooth user-profile flow: new users must be able to register, sign in, view, and edit their own profile. Aside from that, the interface can stay minimal for now; clean, extendable code is what matters most. The build should target Android only. Kotlin plus the current Android Studio toolchain is my first choice because of its modern language features and Jetpack support, but I am open to well-argued Java solutions. For data persistence and authentication you may suggest Firebase or another secure, mobile-friendly backend as long as setup instructions are part of the handover. Deliverables I expect: • A release-ready APK I can install on any recent Android device • The complete, organised source code with clear comments • A concise README covering environment setup, how to swap backend keys, and any build commands When you bid, please share a short outline of your approach, preferred architecture, and an estimated timeline so I can gauge fit and plan the next milestones.
