Critique and refine the existing UI design on my portfolio

I'm a professional developer who designed the UI of my portfolio but I'm not a professional designer. I need someone that will help me spot mistakes that I made and refine the rough edges to make it look better.

I am looking for someone who can make a black and white, single typeface and spacing first design; the whole idea of the website is "less is more"

The Website is https://www.barely.engineering
