I think your page looks great! I really like how each view shows a different map in the header.
I have a few suggestions for you:
Remove the 5px border from the body. I’m not sure if there’s a reason that’s there, but it’s distracting to me.
On your homepage give your Skills and technologies used section more breathing room on top.
I would also maybe argue that the skills and technologies section on your homepage is not adding much value to the page or the portfolio. I think people viewing your portfolio (potential employers) would prefer to see your work.
Right now I have extra clicks to see your projects. The projects are the meat of the portfolio and now they’re kind of hidden.
If you move them to the homepage maybe in each project description you can list the technologies you used in the project. So that way the information is still there, but you’re showing your work, not just a list of logos.
