Cross-Platform Social Media App

I need a complete social-media application that runs smoothly on both iOS and Android. The core experience must include:

• User profiles with avatar, bio and follow system
• Real-time messaging (one-to-one and group)
• A scrollable feed with news/updates, likes and comments

On top of that baseline, I want modular sections that echo the best parts of today’s leading networks:
• Short-form video discovery similar to TikTok
• Micro-blogging posts in a Twitter-style timeline
• Photo-centric sharing like Instagram, including stories/reels
• A rich-text blog post area for longer content
• End-to-end encrypted chat comparable to WhatsApp
Also includes youtube type movie show, channel create, hype feature, subscribe system
verified symbol of popular creators must be included

Expect a modern, scalable architecture, clean code and a functional prototype that I can test on real devices before we move to final polish. Push notifications, social log-in and basic analytics should be wired in from the start. I’m open to proven stacks such as Flutter or React Native with a Firebase, AWS or similar backend—let me know what you recommend and why.

If you have built social apps before, please share links or screenshots along with a concise breakdown of your role and the tech used. I’ll shortlist based on relevant experience, clarity of technical plan and ability to communicate progress in regular milestones.
