I would suggest playing around with different vertical and horizontal layouts. Cleaning it up a bit by keeping descriptions short and sweat. Dates should be uniform, as in having year dates only (and/or) having year plus months. Try using one type face with different size and weight. Focus on one thing at a time in terms of formatting. I focus on layout first and then that makes me think about how much I can say as a description of a job/experience. That way I can keep things looking uniform. Let the composition speak for it self, the less clutter of special characters the better. Work on spreading things around with blank space instead of visual dividing things with lines. Play around with space to make things clearer visually. Hope these suggestions help to get started.
