These designs you linked are more modern than the others that I've seen. It made me realize that there is a lot of nostaglia - either utter minimalism or vaporwave - floating around in personal pages right now - which I do enjoy. But these go in giant page directions. Another good example in this direction is: http://aaf.nyc. It's not a long page, but has a large feeling.
The site you've linked has great videos in the background and I like the animated logo, that really helps in making it interesting.
Personally, I still prefer those sites I've linked, because I know that they are harder to make than those minimalistic/no-css sites. I think it depends if it's a backend dev or a full stack web dev with a focus on UI/UX. In the latter case, it's a good way to show off what you're capable of. With those minimalistic designs (some of them also have bad UX) I don't really know if they're able to create modern, responsive and more complex websites.

Those are experiences. I'll update my website to be so awesome when I get some time for it (bit difficult while managing a team).
My own site, wanted to update it ever since. Not really an eye-catcher, I know. It uses Grav CMS, it's a great CMS (and file-based).

Would love to hear some feedback, especially browser quirks.
