To ensure code quality, I actively participate in code reviews, utilize automated testing frameworks, and follow best practices such as writing clean, maintainable code. I believe in the importance of peer feedback and use it as a tool to enhance our codebase continually.

I typically use Redux for state management in complex applications, as it helps maintain a predictable state across components. I understand the principles behind state management and can switch to Context API or simpler methods for less complex apps when appropriate.

For performance optimization, I focus on writing efficient code, minimizing unnecessary re-renders, leveraging lazy loading, and employing memoization where applicable. Additionally, I keep an eye on the overall app bundle size and monitor performance metrics for continuous improvement.

Some common challenges include dealing with platform-specific issues, ensuring compatibility with native modules, and optimizing performance for diverse devices. I approach these challenges by leveraging the community for shared solutions and maintaining clear documentation throughout the development process.

I have extensive experience using Git for version control, including branching strategies, pull requests, and continuous integration practices. I use Git to maintain clean project history and ensure smooth collaboration with team members during development cycles.

Common design patterns I use include MVC for structuring my applications, MVVM for data binding, and the Singleton pattern for managing shared resources. I always choose the pattern that best fits the project requirements and facilitates code reusability and maintainability.

I prioritize features based on user feedback, business needs, and implementation complexity. My goal is to ensure that the most critical features are developed first, creating an MVP that meets user needs while allowing for iterative improvements based on continued feedback.

I utilize RESTful services by structuring my API calls with proper endpoints and handling requests/responses efficiently. I ensure to implement error handling and use Async/Await for cleaner code when dealing with asynchronous operations.

I typically use Jest for unit testing due to its simplicity and integration capabilities with React Native. For end-to-end testing, I prefer using Detox, which allows me to simulate user interactions and ensure the app performs as expected under real-world conditions.
