Vitor is a full-stack software developer who always strives to produce simple, clean, and reusable code that meets a project's needs. He's been using the .NET framework stack since its release. In the last few years, his deepening interest in scalable systems has led him to Node.js, Angular, and its ecosystem. He likes learning new technologies almost as much as he likes listening to 70's music which is a lot!
