Android Configuration

Hi there What function do you need to be running in the background? I am an Android and iOS expert with a deep experience in building apps in Java and Swift, also, I have a good experience in building apps using hybrid languages like React Native and Flutter and Kotlin, by hybrid languages you can have both Android and iOS versions using one code. Also, I can build the backend using Node.js and MongoDB or Google Firebase. Please contact me via chat to talk more about the project details. Also, I will support the app for 6 months for any bugs. Thanks Best regards Nick
