There seem to be a lot of problems on mobile. You have CSS breakpoints set for smaller browser widths but for some reason on an actual mobile device you see the full width site.
Here are some screenshots from an actual mobile device:
As you can see, there are elements overlaying and cutting off text and images. The images in the mobile device illustration are overflowing the devices bounds and don't scroll like intended.
What I'm assuming is the intended mobile design has some issues with spacing.
Here are some screenshots as they are now: (these are from a desktop browser with the window at a small size - not on a mobile device)
I have highlighted some areas that have spacing issues.
A quick edit to address some of the spacing issues:
The prev/next buttons on the projects also have some strange behaviour where sometimes it shows two sections, one above the other then shows one after navigating:
There are some design issues. The color scheme in general is ok, the only issue I would say is the 'View Project' button. The color isn't very pleasing or inviting, and the it isn't obviously a button. I would personally use the existing green and either make it more of a button or at least give it some indication of action.
I would also tone down the drop shadows on everything, and maybe add a faint stroke as well to the project sections.
This is a quick mockup of some of the changes I would make:
As I said, that is a quick mockup, but it gives you an idea of what I mean.
But, before worrying about any design changes I would focus on functionality. Since you are looking for UX jobs I would spend a lot of time testing and getting everything working correctly as it is not good in terms of mobile UX as it is now. Anything that doesn't work as expected will be an instant turn off if you are looking for UX work. It's like going for a plumbing job and showing them leaking pipes as examples of your work.
