Can someone with some experience help me?

Hello, world! My name is Luiz and I'm a Brazilian lawyer who is trying to be a self-taught software engineer. So, I’m studying have one year now, and I’ve decided to give the leap of faith to focus all my efforts on getting a tech job because I’m really in need. That said, I’m doing the CodeNewbie challenge and I need one or two of you to help me out with my first mission. So, if possible, I want some sincere feedback on my GitHub (#roastme).
