We are looking for a seasoned React Native developer with a strong background in performance optimization and code refactoring to upgrade and enhance our existing mobile application. Our app is currently built with React Native version 0.69.3 and requires a series of improvements to ensure a seamless and efficient user experience. Primary Objectives: 1- React Native Upgrade: Update the app from React Native version 0.69.3 to 0.72, ensuring compatibility and stability throughout the app. 2- Performance Optimization: Address the slow navigation issues between tab screens, with a particular focus on enhancing performance on Android devices. 3- Component Efficiency: Reduce unnecessary component reloads, especially in scenarios like opening a comment modal in the feed screen, to improve app responsiveness and reduce lag. 4- Code Refactoring: Undertake a comprehensive code review to identify and eliminate code duplications. Implement a more modular approach using components to streamline the codebase. 5- API Call Management: Standardize API call methods by defining utility functions. Transition from a mix of fetch and axios to a consistent approach, reducing code duplication and enhancing maintainability. 6- Multi-Language Support: Fix bugs related to the multi-language library, ensuring the app consistently displays the correct language selection.

Hello, To address the technical challenges, I will initiate a seamless React Native upgrade from version 0.69.3 to 0.72, ensuring optimal performance and stability. Additionally, I'll tackle the slow navigation issues on Android devices by implementing targeted performance optimizations. Two questions for further discussion: How critical is it for the app to maintain backward compatibility with older versions of React Native during the upgrade? Regarding the slow navigation on Android, are there specific user scenarios that exhibit more pronounced performance issues? Let's connect to explore these aspects further and discuss a tailored approach for your project. Best regards, Jacob H.
