react web and mobile app

I'm looking for a Freelancer to create a React web and mobile app with functionality for user accounts. I don't have a specific design in mind for the app, but I have some ideas for how it should look. I would like it to work on both web and mobile platforms. The app will also need to have payment integration as well as real-time updates. If you have experience with React, please get in touch. I look forward to hearing from you!
