The typeface with its wispy horizontal strokes is murder to my eyes. It's an extremely poor choice for on-screen legibility with such a text-heavy resume.
Wall-of-text syndrome, compounded by poor typeface legibility and total document length.
Who is your audience? As an engineer, my overall sense is that I wouldn't hire you for a very technical role. If that is a correct assessment of your skills or if your intended audience isn't engineers then that's okay.
One thing I noticed was your bullet point on fixing a cron job. You stumbled upon a bug with, as it turns out, important ramifications. The way it's written makes it seem like you're trying to bullshit non-technical people into thinking this was a technically impressive feat rather than a stroke of luck. I get you're trying to make a case for your value to the business, but I frankly find it odd.
You might want to proof-read it better. As a random example, "document how everything service worked" clearly has something missing.
