Software development hybrid application

I am looking for an experienced software developer to build a hybrid mobile application for Android and iOS platforms with user authentication, and in-app purchases. The key functionalities that are needed in the application are user authentication, in-app purchases, and live streaming. I would like to have this project completed within less than a month. The developer must have experience with developing hybrid mobile applications and must have a portfolio to demonstrate their expertise. The developer must be able to provide suggestions for improving the application based on their experience. If you think you are the right person for this project, I invite you to work with me.
