My first project using React JS

This project took me a few days and it was very challenging. I'm very satisfied with the result even though I didn't complete some items. I think the code was a mess and it could have more components. Due to the way I created the components, I was not able to make the mobile model identical to the one proposed by the challenge. I used Json Server and deployed it in glitch to work as the app's backend. If anyone can show me how to improve my code. Any feedback is welcome!!
