Flutter/React Native App Build VibeVision

I need a cross-platform mobile application delivered for both Android and iOS within roughly four to six weeks. The stack can be either Flutter or React Native, but whichever route you choose must integrate smoothly with a REST-based API layer and rely on Firebase or MySQL on the back end.

Core requirements:

Email-and-password user authentication

Real-time push notifications

Clean, intuitive UI/UX that feels truly native on each platform

Full deployment support—store listing preparation, signing, and submission

Deliverables:

Fully functional mobile app

Source code in a well-structured repo

Build/run instructions

Concise technical documentation

Evidence of testing (unit and basic UI tests)
