1. Site wasn’t properly reflexive for mobile
2. If this is a portfolio then i would remove a lot of stuff like “watch list” and “current obsession”. The focus should be on your work and future projects
3. Notes are ok for a start but can be improved. I think a “posts” or “blog” would be better section title, and the content should try to teach something you’ve learned rather than be the notes you took for a subject. The difference is that teaching reinforces your understanding of the topic. So pick something smaller from those topics and teach it. I wouldn’t redo your current notes necessarily, but going forward i would pick a more focused topic and teach.
4. i would then move the “blog” or “posts” to your front page to show the most recent content and then link to /posts where the rest of it can be found. Or highlight projects on front page instead depending on what you want focus to be.
5. move your front page content to a more “resume” section that includes a section for the tools you know. And still think about the length/space of this page. Like a printed resume, too long is bad. So make sure it outlines things nicely

Overall if it was just a personal site id say its ok. But as a portfolio site you have some work to make it align with your goals. Good luck!
