I just have a few grammar suggestions:
Web Development: Since From a young age, I have ....
Skills: I have knowledge in responsive web design with experience in:
HTML, CSS, JavaScript, jQuery, Bootsrap, Node.js, Python, AJAX, Angular, Visual Basic and am learning more every day! (or ..., Visual Basic, and I am learning more every day!)
As to Athletics and Hobbies - Is the site about you, or is is there to get you web development work? If it's you - then fine, but if it's there to get you work, I don't see how any of that is relevant at all. If I'm looking for a plumber, I want one who does good work, and I couldn't care less if in his spare time, he's bird-watching or under-water-basket weaving.
And from the 'Need a Website?" part:
If you need a website that looks great on all screen sizes, you've you have come to the right place. I work with a small team of developers, and we would love to get you started. We aim to make the process as easy for you as possible, leaving the work to us while keeping you posted every step of the way. We aim to make the process as easy for you as possible. Leave the work to us, and we will keep you posted every step of the way. Our goal is to make your dream site come to life, and we wont will not stop until you agree! Get in touch with me (see below), and we can discuss the details.
None of this is a big deal, and most people probably won't notice, but grammar nazis like I am, will :-)
