Hi there😊, I'm Zion 👋 I like to write, and I like to build stuff. Most of the articles on my blog are themed around JavaScript; however, I will write articles talking about data science, machine learning/artificial intelligence, or expound on a project I'm working on. Take a tour of my blog, see what intrigues you, and I hope you stick around for more!
