Hello there,
I looked at the PDF you attached, which was the design for your app. This project looks really appealing to me as you need a backend also that goes with the application. As a whole, you want a complete product from me, which I prefer being a full stack developer. I have already built applications with React Native previously and developed backend APIs that work together flawlessly. I would love to do this project for you. Let's talk so we can discuss further. I will be waiting for your response.
Regards,
Aseem Regmi
