I see the hamburger menu icon isn’t working and only toggling the nav-links.
Does it serve any purpose?
My idea would be to make it display only when the website hits the mobile view.

This is one amazing portfolio.
There is just one problem. when I hover over your email, the spacing glitches itself to death.
