Learning Node.js opens multiple career paths, including Node.js developers, back-end developers, full-stack developers, and open-source software engineers. Many people start their careers as front-end developers, moving into the role of senior developer after gaining a few years of experience. In this case, you could become a scrum master, team lead, or architect. You could also branch out into management roles, such as team or line managers, or you could create your own consulting business or startup.
