Full-stack web development covers both front-end web development and back-end web development responsibilities. Depending on the complexity of a website, a full-stack developer may be responsible for all facets of its development, from the server side to the user interface. Many full-stack developers may still specialize in one aspect of web development, but their broad experience is useful in troubleshooting or speeding up a build or redesign. Full-stack developers are often responsible for identifying cutting-edge technologies, such as enhanced programming languages and blockchain, that can be used to strengthen websites’ business capabilities.
