Back to original languageAbout Leandro
Hello! I'm Leandro, a full-stack developer mostly focused on the frontend.
Ever since I was young, I've been passionate about technology. Starting in elementary school, I began studying basic computer concepts like MS-DOS, Windows, and the Office suite. During high school, I studied PC assembly and repair, hardware and software configuration, among other things. It was great and I enjoyed it a lot, but when I discovered web development, I knew I had found my place. Since then, I've dedicated myself full-time to developing content that not only looks great but also (and most importantly) functions perfectly.
If you're interested in talking about technology or exploring potential collaborations, don't hesitate to get in touch with me.
