Thanks for sharing these tips! A thought about your resume: the contrast is so low for your right column content that I didn’t even read it because I was straining so hard. Same goes for your footer info with your email and portfolio link. No doubt this is information you want reviewers to know!
I would add a tip to this post that accessibility of your content is as important as the content itself. Accessibility basics like color contrast will have a huge impact on the legibility of what you’re sharing. Best of luck!
