The titles of the projects should have hierarchy (different sizes, for example)
Put your social media links both at top (header) and the bottom (footer). (Maybe not put Instagram link, only if it can stronger your personality or it's UX related)
Some examples from the reviews
Home hero title at the beginning of the homepage & social media links at header
Each Project
Key deliverables at the beginning
Show numbers and data in your portfolio
GIFs, videos, or prototypes links make the work interesting and eye catching
Don't need to put everything on you case (persona, every tool). If you put it, you have to know the rationale why you used this tool or method
"What is the problem?" Have to point out on the page
Showing some complex system screenshots can stand out. And it should be clickable to zoom in for people to see what it is about
Underline/ bold the key points. They are good to have, just don't use it too often
If the text are a lot in one section, try to have more blank space (break it into more paragraph) or add a image (infography) for readability
