hi, good start, simple and clear. It can be confusing as you can see per the above comments. There's another downside of having the information available on hover only, it is that it will fail on mobile.
+ the projects you have worked on, look interesting, I'd be intrigued to find out more about the projects and processes, so I hope it is works in progress - wouldn't mind a bit of info should this be the case. Portfolio is a hard piece of work, so keep up the good work and grow it!
I wanted to just address the bio section, everything feels really cramped so I removed the left/right padding to make it a bit wider, increased the line-height of the paragraph text to make it more readable and attractive, gave it some top-margin, and altered the location text to be all-caps with some letter spacing to create more of a drastic hierarchy instead of all the text looking 'slightly' different. Hope that helps!
