Looking for resume feedback

I'm applying for a very short-term remote teaching job. Google apps is in the tech section because they specifically asked for it--guessing that's not standard but curious to know if it is for future applications. What could I improve? https://imgur.com/a/QPNM3oA

They are also looking for strong writing skills, which I have but can't demonstrate through any of my work experience. Any advice on how to incorporate that, or should I just list it as a skill?

(I should note that the font doesn't have this italicized look once I save it as a PDF. I know it looks a bit odd in the pic because of that. The only thing that's actually italicized is the dates.)
