But seriously, hanging indents, a very minor textual hierarchy, your Masonry layout is messed up, etc.

It all looks very unprofessional. KISS is your friend unless you are a master of making these complex responsive sites. Fix your voice, too. This is your site. Don't write it like a biography if the site itself is an autobiography (unless you're really funny and clever about it, which you aren't).

The purpose of a site like this is to allow people to find out more about you. What you've done mashed your entire professional life into a really, really long document that only looks passable on mobile phones. Figure out what you want to say. Make it CLEAR. Use CONTRAST. Put those pictures on your flickr page and link to it.

Personal pet peeve: don't tell me how experienced you are at a certain language or technology with a percentage--show me some shit you made.
