I need a developer who can turn my concept into a fully working Android application. The end goal is a polished, install-ready APK along with clean, well-commented source code that I can compile locally. I will share the detailed user flow, screen sketches, and any required assets once we start so you can translate them directly into the app. Expect to work with the latest Android SDK, follow Material Design guidelines, and keep the codebase modular for easy future updates. Please factor in: • Building all stated features until everything runs smoothly on current Android versions. • Clear hand-off: source, build instructions, and a quick walkthrough so I can reproduce the build on my machine. • Basic testing to confirm stability and performance on common screen sizes. If you have recent Android projects you can show, that will help me gauge fit quickly. I’m ready to get started as soon as we agree on a realistic timeline.
