Perhaps break up the hero text into a headline and paragraph. It's a lot at once/in the same mass.

Your text on project detail pages does not contrast very well and could be an accessibility problem.

I agree with Vadim to add some hover styles so it's clear what is interactive.

Also I really despise "contact" links that are just mailto. It's not clear that's the action that will happen unless I pay attention to the browser tip in the lower bottom. Perhaps just put the email address itself so it's clearer or set up a contact form.

Likes: the gradient/ minimal aesthetic is nice.

Nice site! Your first fact is false seeing as you have GA ;)

I'm happy they finally updated. How ironic it was to have 'modernizr' name and such an out of date site ... Also love they're using React for the build tool! The list of items is a bit daunting without filtering them, though...
