Java Developer building scalable systems and modern web applications

Java Developer building scalable systems and modern web applications

Hi, I’m Marco :)

I’m a Fullstack Developer with strong expertise in Java, Spring Boot and Web Development.

I’ve worked on enterprise platforms, e-commerce solutions, and custom web systems, combining solid engineering practices with practical, real world problem solving.

A young man with curly dark hair and earrings is shown in four photos wearing a black and white striped shirt. The photos are arranged in a 2x2 grid. In the top two photos, only the upper part of his shirt is visible, focusing on the stripes. In the bottom left photo, he is making a peace sign with his right hand, holding it near his face while looking directly at the camera. In the bottom right photo, he is again making a peace sign with his right hand, but this time placing his hand near his forehead while slightly tilting his head.
