I’m looking to have a custom Android application built from the ground up. The core requirement is native Android support; iOS is not in scope for this phase, so all design, coding, and testing should target the latest Android SDK standards. At this stage I have a functional concept and a basic feature list, but I will rely on your expertise to refine the technical architecture, recommend the best tech stack, and turn the idea into a smooth, production-ready app. Deliverables should include: • Source code with clear, maintainable comments • APK and signed app bundle ready for Play Store submission • Brief setup documentation so I can run the project locally or hand it to another developer if needed Clean UI/UX, responsive layouts across device sizes, and solid performance are important to me. If you have experience integrating RESTful APIs, Firebase, or similar backend services, please let me know—that will be a plus. Feel free to share links to previous Android apps you’ve shipped, along with a short note on how you typically manage version control, testing, and post-launch support. I’m ready to start as soon as I find the right developer.
