Looking for a Mobile App Developer

My client insists on a hybrid app but not sure what is best. You can suggest what is the best hybrid now(client is considering about react native, ionic, flutter). Backend APIs are currently preparing and you can work with the backend developer. Design is ready, I uploaded some designs for you to get an idea of the project. Please send me your proposal. - Your Rate - Timeline - What platform are you going to build? And why? - Show me the best project you have done. - Are you willing to work on the weekend also, if needed? (it can be counted as much as you work) - Have you got any question? Thanks in advance.
