I am only going to focus on language and wording, and I hope you find it relevant.
I think you achieve a pretty good balance of speaking of past experience that led you to where you are, and adding also a few words on personal interests. But trying to think like someone looking to hire, I am not too sure I see what your specific focus for the future is. You write “… determined to dedicate myself to learning as I pursue a career in what I love.” But after that you speak no further on how that career would look like,. You mention programming of course, but that is a very wide encompassing term. What kind of programming?, What kind of projects or problems do you enjoy working with? Are you looking for employment or are you available for freelance gig? Have you done any commercial work already? You do list the technologies further down in your portfolio but they don’t tell a story of you.
I hope that gives you some thoughts on how to work on your portfolio.
