Cross-Platform Social Media App Development -- 2

I need a skilled developer to take a new social media idea from concept to fully published mobile apps that work smoothly on both iOS and Android. The core of the job is to design, build, and deploy the entire application stack—mobile front-ends, backend services, and the basic infrastructure required for secure sign-up, real-time interactions, and ongoing content updates.

Here is what I already know for sure:
• Target platforms: Both iOS and Android, released to the App Store and Google Play.
• App category: Social Media.

Everything else—from interface details to feature roadmap—will be shaped with your guidance. I am looking for modern, maintainable code (Swift/Kotlin or React Native/Flutter are all acceptable), clean UI/UX, and a scalable backend architecture that can grow as the user base expands.

Deliverables I expect:
1. Source code for the mobile apps and server.
2. Working builds ready for TestFlight / internal testing on Android.
3. Deployment scripts or clear step-by-step instructions to push to both app stores.
4. Basic technical documentation so future developers can pick up the project easily.

If you have a proven track record launching social platforms, please include relevant examples. I’m ready to move quickly once I find the right fit—let’s discuss your approach and timeline.
