Hi there. I have read your job description carefully and it's very interesting to me. As an react-native developer, I have rich experience and knowledge about android and ios development. I have developed many mobile apps by using React Native frameworks such as React Native Elements, NativeBase, React Native UI Kitten, Lottie For React Native, React Native Maps... and used Node.js, Laravel, Firebase, MongoDB as backend and database. From my past works, I'm sure that I can successfully complete your work. Looking forward to hearing from you.
