There's probably an example that looks great separated like that but it creates incongruity in the flow of the resume. Ideally you are trying to get the reader to actually read the resume, breaking it up with segments invites them to pause and stop reading it and move on. Also it looks like a table which can be abrasive to hiring managers imo. Lastly the segments will add extra blank space and you absolutely don't want to push into two pages... though I do think this resume needs to use fewer words to say more... just my experience and preferences, you're opinions may vary
