Portrait of Leonardo Capitani Pansonato

A bit about me and my journey in programming.

I've been building web projects for about 4 years, starting out coding in HTML, CSS, and JavaScript with a focus on the front end. Since then, I've kept improving by studying modern, up-to-date technologies.

I'm currently a fullstack developer with extensive experience building complete apps, from secure and scalable backends to modern, intuitive interfaces. My biggest goal is to create projects that have a positive impact on people's lives.
