Requirements

• Proven track record as a React Native expert, with deep knowledge of the ecosystem (navigation, state management, native modules, performance optimization)
• Demonstrated ability to start a mobile project from scratch: bootstrapping, architecture decisions, CI/CD setup, and store deployment
