Yeah, if you can come up with a way to give the viewer a "sense" of the person at a glance it would go a long way. Maybe add colors? Or maybe consider that some metrics are pretty related and could be represented separately. Frontend / backend could be represented as a continuum by itself. UI/UX are sort of tied with front-end, so coming up with a way to link those together might be nice. Perhaps you could use the data you have to see what tends to be linked together and come up with 2-3 representations that communicate what you're going for quickly.
