Cross-Platform Social Microblog App

I’m ready to move from idea to working product on a new social platform centered around bite-sized posts. Users will be able to publish short updates, follow their favorite creators, see a live feed, and stay engaged through real-time notifications. A built-in private one-to-one messenger should let them exchange text alongside photos, videos, and other files without ever leaving the app.

The experience needs to feel identical on Android phones, iPhones/iPads, and in any modern desktop browser, so a shared codebase or closely aligned native builds are essential. I’m open to React Native, Flutter, Next.js, or another cross-platform stack as long as performance is smooth and maintenance remains straightforward.

Deliverables I’d like to receive:
• A fully functional MVP for Android, iOS, and web
• Clean, well-documented source code in a public or private repo of my choice
• Basic admin tools for user moderation and content reporting
• Setup instructions plus a brief hand-over call to walk through deployment and future scaling options

If you’ve shipped cross-platform social or messaging products before, show me what you’ve done and let’s discuss how you’d tackle this one.
