Bottom sticky navigation on iOS can be frustrating. This isn't just your site, many fall into the same trap.

Whilst it's easily reachable, scrolling hides the Safari UI and the sticky nav changes position. Tapping on the screen reveals the UI again and again the navigation changes position. Often you have to tap twice to get to the desired location.

It works for native apps but less so for websites.

I'd like to see less animation, and as a hiring manager I tend to look for more details in case studies. Overall a great portfolio, but those things would clean it up and take it up a notch.
