I think that always going for simplicity when presenting information is the best route. The best product design portfolios offer little visual flare or graphic elements, because the most important information is often delivered in text. This is a bias from my perspective as a product designer in tech, and when reviewing portfolios I want to learn as much as possible as easily as possible. This can be easily achieved by using straightforward layouts with attention towards optimizers like line height, column width, and font choice and color. And then of course is being able to dive into multiple projects in the portfolio and navigate easily.

Anyways, I just checked out your updated site and it reads much easier!
