A Full Stack Developer is a versatile professional skilled in both front-end and back-end web development. They have the ability to design and develop the entire web application, from creating user interfaces (UI) to managing server-side logic and databases. On the front end, Full Stack Developers work with technologies like HTML, CSS, and JavaScript to create responsive and interactive web pages. On the back end, they use server-side languages like Python, Java, or Node.js, and databases like MySQL or MongoDB to handle data storage, processing, and application logic.

Full Stack Developers are also familiar with version control systems like Git, and they often use frameworks like React or Angular for front-end development, and Django or Express for back-end development. Their broad skill set, often honed through a full stack developer course, enables them to oversee a project from conception to deployment, making them highly valuable in the development process, capable of handling complex web applications and ensuring smooth integration between the front and back ends.
