Front-End Developer vs. Back-End Developer vs Full-Stack Developer
Modern web applications consist of two major parts: the Front End, which users see and interact with, and the Back End, which handles business logic, databases, and server-side operations. A Full-Stack Developer has the skills to work on both.
Front-End Developer
A Front-End Developer builds the user interface (UI) and user experience (UX) of websites and web applications. Their primary responsibility is creating visually appealing, responsive, and interactive applications that users can access through a web browser.
Front-End Developers focus on what users see and interact with.

Back-End Developer
A Back-End Developer builds the server-side components that power web applications. They develop APIs, manage databases, implement business logic, and ensure applications are secure, scalable, and reliable.
Back-End Developers focus on how the application works behind the scenes.

Full-Stack Developer
A Full-Stack Developer is proficient in both Front-End and Back-End development. They can build complete web applications, from designing the user interface to managing servers and databases.
Full-Stack Developers are often responsible for delivering an entire application independently or collaborating across multiple development teams.
