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).
And the website of my agency (it's German)
Would love to hear some feedback, especially browser quirks.
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.
