Building a web app

I have a project to do and i have to make a technical project. I am making a project for my cleaning business. And i want to make a web app(project management web appplication) and i was thinking of making it with amazon aws but i can do it either way and i have to show the steps on how i did it because i am going to make a presentation about it. If you could do a video or list the process of how it was done so i can prepare for it would be cool. I already made one on Monday.com but my teacher said it was too easy and i had to make it from the scratch.
Attached is a picture of the type of web app i need.
