Cross-Platform Community Messaging App

I’m building a mobile space where customers and service providers can connect for real-time support and conversation. The heart of the product is messaging: users will hold one-to-one chats, spin up group discussions, and post to wider community threads while freely sharing photos, videos, and other files. I need an experienced engineer who can own the full build for both iOS and Android from a single codebase.

Key elements you’ll implement
• Secure sign-up and login with Email, Google, and Apple ID
• Role-based profiles (Customer, Service Provider, Admin) that unlock the right screens and permissions
• A clean, intuitive interface with searchable lists, rich detail views, and live data updates
• Push notifications that alert members to new messages, group activity, and account events

I’m flexible on the tech stack—Flutter, React Native, or any comparable cross-platform toolkit—as long as it delivers native-grade performance. Real-time messaging and file handling can run on Firebase, AWS Amplify, or a solution you recommend. Design polish matters; I’ll provide brand colors and starter wireframes, and I rely on you to refine the UX so first-time users feel at home immediately.

Deliverables
1. Fully functional iOS and Android apps, ready for App Store and Play Store submission
2. Lightweight admin panel or API endpoints to manage users, roles, and reported content
3. Well-structured, documented source code and a brief hand-off guide
4. Post-launch support window for defect fixes and store approval adjustments
