Full Stack Web Development involves building both the front-end (what users see and interact with) and the back-end (server, database, and application logic) of websites and web applications. A full stack developer works with technologies like HTML, CSS, JavaScript (front-end) as well as languages and frameworks like Node.js, Python, Java, databases, and APIs (back-end).
They handle the complete development process—from designing responsive user interfaces to managing data and deploying applications—making them versatile and highly in-demand professionals.
