A bit about myself

Hi there. As I mentioned before, I'm an economist turned engineer. I started studying economics back in 2020, but, 3 years after starting the degree, I realized that my passion was in the tech field. I learned almost all I know about programming by myself, and I've been working really hard to get to where I am today.

About me personally? I'm really into the world of product design and tech trends, and I love a good chat about anything tech. When I'm working on a project, I'm all in, aiming to make things as great as they can be for the people using them.
