I already have the first cut of my social-media MVP running on both iOS and Android, but it still needs that extra polish before we can unveil it. The codebase is in good shape; what I need now is an experienced mobile developer who can: • Refresh the user-interface so it feels crisp and consistent • Smooth out navigation and overall user flow • Tighten up the remaining backend logic and connect everything to Firebase for auth, real-time data, and push notifications You will receive the existing project files as soon as we sign a mutual NDA. From there, your task is to refine the current screens, hook up the data layer to Firebase, run end-to-end tests on both platforms, and make sure the build is App Store / Play Store ready. If you have a track record of shipping production-ready React Native, Flutter, or native Swift/Kotlin apps that leverage Firebase, I’d love to see examples and hear briefly how you’d approach this hand-off. A concise walkthrough of similar projects is all that’s needed; no lengthy proposal required. Milestones will be tied to interface completion, Firebase integration, and final build approval. Look forward to collaborating and getting this app over the line.
