My name is Jeferson Barrero, but my friends call me Jef. I started programming at the age of 14 as a self-taught enthusiast, inspired by figures like Freddy Vegas and by exploring the web. This early dive into the fascinating world of programming shaped my journey.
As a PLATZI student and a participant in the 'MisiónTIC2022' project since its pilot phase, backed by the Colombian government and MINTIC, I have built a solid foundation in programming and web development. Actively participating in personal and collaborative projects with clients has been essential to honing my skills as a developer.
Adding to this journey with virtual courses from SENA and my current studies in 3D modeling for industry and administrative assistance, I aim to stand out in the field of web development and programming. My vision includes not only personal growth but also actively contributing to the community. As a contributor on GitHub, I participate in projects aimed at promoting free and open programming education.
