I tend to think resume advice is overrated. There's so much variability in how companies screen them, who reads it, what they care about, and how they get read. People tend to give advice based on their idea of what a good resume should be like, but it's very difficult to properly measure how good some advice is. Saying "I'm not surprised his job search has been unsuccessful when his resume looks like an essay." feels unnecessary when you're overly judgmental on your preferences.
My overall impression of the resume is that it's fine, but I expect a ton of other candidates to have similar looking resumes. If I were to give advice, either create and demo a really interesting project and show it to someone who would find it interesting (maybe they've done related projects themselves), or find new communities and different groups of people that you share common interests with. It's hard to stand out with just a resume alone, and changing formatting and rewriting words don't change the underlying content.
