Hi there! I noticed that you are in need of an experienced Flutter app developer to enhance your existing mobile application, specifically focusing on UI improvements, fixing critical calling issues on iOS devices, and updating the admin portal. My previous project involved a similar scope where I successfully revamped the UI/UX of a mobile app, resolved critical issues, and implemented necessary updates. I have a strong background in Flutter development, a deep understanding of iOS-specific issues like notifications and calling functionalities, and experience with real-time communication features. I am also well-versed in backend development, making me a well-rounded candidate for this project. One question that comes to mind is how critical are the calling issues on iOS devices, and how soon do you need them to be addressed? Understanding the urgency will help me prioritize tasks accordingly. Looking forward to the opportunity to collaborate on enhancing the DigiBells app. Thanks, Tejbir Bhatia
