I need an experienced Android developer to turn my concept for a new social-media app into a functional, polished product. The core idea, visuals, and basic user flows are ready; what I’m missing is someone who can translate that vision into clean Kotlin/Java code, wire it up to a scalable back-end, and publish a rock-solid APK to the Play Store. Key goals • Create a modern Android-only application that lets users create profiles, follow each other, post text and images, and interact through likes or comments. • Implement secure authentication, preferably with Firebase Auth or a comparable solution. • Set up a real-time database or RESTful API for posts, profiles, and notifications. • Handle image upload/compression efficiently so the feed stays fast even on slower networks. • Deliver well-structured source code with clear documentation so future feature updates are straightforward. Acceptance criteria 1. A signed, installable APK that passes Play Console pre-launch checks. 2. Full source code in a Git repo with commit history. 3. Brief README covering environment setup, build steps, and any third-party libraries used. 4. All major user journeys—signup, posting, following, notifications—tested and working on Android 10+. If you’ve launched social platforms before, please mention which libraries or back-end stacks you prefer and share links to past Play Store releases. Let’s build something users will love scrolling through every day.
