Build Android Social Networking App

I want an experienced Android developer to create a social networking app from the ground up. The goal is to give users a smooth space to connect, share updates, and chat in real time, fully optimised for modern Android devices.

Key deliverables:
• Intuitive, Material Design–compliant interface
• Secure user registration and sign-in (email, phone, or social login—open to your best recommendation)
• Personal profiles with photo, bio, and basic stats
• Scrollable feed where users can post text or images and engage with likes and comments
• One-to-one messaging with push notifications
• Scalable back-end (Firebase, AWS, or another solution you propose) plus a simple admin panel for moderation and analytics
• Clean, well-documented code ready for Google Play submission

Please outline your preferred tech stack, estimated timeline, and links to any similar apps you’ve shipped. If you have suggestions to enhance performance or user engagement, I’m keen to hear them.
