Leonardo Mazza

Fullstack Developer

I am a fullstack developer with a passion for building web applications.

About

I’m a Senior Full Stack Developer with solid experience in React, Vue, PHP, and Laravel.

Until recently, I worked on projects for the Government of Portugal, specifically for the Polícia Judiciária, where I was responsible for framework migration, maintenance, and the creation of custom modules and components.

Currently, I’m not engaged in any commercial projects — I’m focusing on personal development by building my own side projects to sharpen my skills and learn Node.js, which is the next technology I’m diving into.

Outside of work, I enjoy exploring new restaurants with my wife and playing trading card games to unwind and stay inspired.
