I feel obliged to give feedback since you mentioned me 😅 , but dashboards are really not my expertise. But I think you don't need to write "Home" at the top because the user can see that "Home" is selected in the left menu bar. I don't understand why you have a schedule in the home section when there is a separate menu for "schedule" on the left menu bar. Anyway, the color scheme is nice. Keep it up, brother.
oh! And I think the toggle buttons need redesign. Traditionally, horizontal padding should be twice the size of vertical padding. Your toggle buttons look weird in my eyes.
Now that I've entered the link and scrolled through your case study, I have some more opinions I'd like to share. I don't think recruiters have that much time to thoroughly read such a detailed case study since they have to process tons of portfolios. And they might get tired of reading a traditional case study like yours since everyone is following the same template. So, my advice is to keep it short and straight to the point, and add a personal touch. The visual or UI of your case study is perfect; it's the experience or UX aspect that you need to work on, in my opinion. Hope this helps.
