I can't remember the URL, but the most incredible CV I saw was with animations, you controlled a guy that walked while telling all his knowledge. It was really impressive. I think that those kind of sites shows little about what can a dev do. You can lie about what you know (and I saw lots of CV that I'm certain they're lying), and you can't have a big site just to tell what you know, you can't use React or Angular, you just need a static page.
