What does a freelance full stack engineer do?

A Freelance Full Stack Engineer is a self-employed software developer who is skilled in both front-end (client-side) and back-end (server-side) technologies. They design, build, and maintain complete web applications or websites, handling everything from user interfaces to databases and server logic.
