A Full Stack Developer is a professional with expertise in both front-end and back-end development, capable of working with various technologies and programming languages across the entire web development stack. In essence, a full stack developer is well-versed in both client-side and server-side development, allowing them to create end-to-end solutions for web applications. Their skill set typically includes proficiency in front-end technologies such as HTML, CSS, JavaScript, and front-end frameworks (e.g., React, Angular, or Vue.js), as well as back-end technologies such as server-side languages (e.g., Node.js, Python, Ruby, or Java), databases (e.g., MySQL, PostgreSQL, MongoDB), and server management. Full Stack Developers have a comprehensive understanding of how different components of a web application interact and collaborate to deliver a seamless user experience.
