To become a full-stack developer, you need strong knowledge of both front-end and back-end technologies. For the front end, learn HTML, CSS, JavaScript, and frameworks like React or Angular. For the back end, understand server-side languages like Node.js, Python, Java, or PHP, and databases like SQL and NoSQL.
