Love this article! I spend a lot of time just experimenting with my profile and my portfolio website because I think building a personal brand image is important. It helps you stand out online, among the sea of thousands of developers. It also adds flair and personality, which I love! My website (and my GitHub too) have actually helped me get most of my jobs.
Here's my GitHub: https://github.com/AidanSpeakss
And my website is linked on my Github if you are curious.
And here's a few Repo's that might help spruce up your profile:
