Hello, I'm

Vitor Martins

Senior Backend Software Engineer

I’m a brazilian software developer, that believes in the power of technology should be centererd in improving people’s lives.

Beyond coding, I’m an avid reader and passionate about cinema. I’m also into city-building video games, where creativity and strategic thinking come together. Music is a constant companion in my life—especially when I’m spinning tracks from my growing vinyl record collection, that helps me disconnect a litte.

I’m always eager to learn, create, and contribute to projects that make a real difference.
