I am searching for a skilled Flutter developer to address the performance and functional issues experienced with my existing code. The key problems lie within the area of user authentication and data fetching. The backend is a custom setup using RESTful API. An understanding and proficiency in API integration is therefore essential. The flows that need debugging are: - Performance issues: The application is slower than expected, and I need someone to optimize its efficiency. - Functional bugs: Particularly with user authentication and data fetching. They don't always work as indented, and I am looking for someone with detailed knowledge in Flutter to troubleshoot and correct these issues. Ideal Skills and Experience: - Strong experience in Flutter development - Good knowledge in RESTful API integration - Exceptional debugging and optimization skills - Prior experience with similar tasks. Please, only apply if you have deep understanding of Flutter and RESTful API integration.
