I don't want to be rude, and I'm certainly neither a designer nor a real typographer, but IMO this looks awful.

First decide on a good page area. The margins are much too small.

Regarding whitespace: you need more. Much more. Especially between the two columns. Everything is flowing into each other. Look at "Over 1000 lines" and the next line, for example.

You probably need to cut quite some of the information presented. That's okay.

I don't understand which criteria underlie the categories' sorting. "Education" and "Coursework" is interrupted by "Links". I think those category headers should stand out more, but the problem may well be too few whitespace. Again.

Basically you really have to go looking for information, nothing is really standing out and guiding you to what you'd like to see.

Is "%ile" common? It looks a bit gimmicky, but I'm not sure about English microtypographic usage there.

But it is probably still way better than most CVs.

As someone who actually conducts interviews i must agree with you. I recently interviewed a girl who was actually very talented but her resume looked very much like the one in the link (maybe she actually got it off of there). I looked at her resume and thought in my head this is one the worst looking resumes i have ever seen. I did recommend hiring the girl because she was a talented developer, but the resume looked hideous.
