I would like to say great minds think alike! I actually built the side project with the same idea as you. Literally I named it ELI5programming. Although yours has a better frontend by a mile.
I'm super interested in studying at the moment. For years I suffered from hypogonadism, making it difficult for me to function as a human being. I'm trying best to pursue my interested in Computer Science at the age of 27. Hopefully it isn't too late!
