i want to configure react native code with ios and android configuration

Hello, I am looking for a developer who can help me configure my existing React Native code to work with both iOS and Android platforms. I already have the code but need assistance in deploying it. The developer should be familiar with both platforms and the process of deploying React Native applications. This is an important project and I would highly appreciate anyone who can help me get it done. If you feel like you can help me successfully configure the code for both iOS and Android, please contact me as soon as possible. Thank you!
