Custom member pages

I have a idea I want to create but struggling with how to go about it, I’m wanting a user generated content section (a bit like when you click on a users instagram profile you get the pics and can swipe to tagged pics) but I’m wanting the content to be

1. Only the user who created the content can edit it
2. The content needs to be different depending on user choice (these will be block like in wappler but my own styles) one user might want 3 column of text another might want a image gallery another might want both aswell as more of these options.
   How would I create this as to where lets say a user creates a project on the site gives it a name this would then give them their own page under that project name to edit etc. Would I need to make a new file per project the user creates?
