A web developer is a skilled professional responsible for creating and maintaining websites. They use a combination of coding languages, such as HTML, CSS, and JavaScript, to design user-friendly and visually appealing web pages. Web developers also ensure websites are responsive and functional across various devices and browsers. Their expertise extends to back-end development, where they work with databases and server-side scripting to power the site's functionality. With the ever-evolving digital landscape, web developers play a crucial role in shaping the online presence of businesses and individuals.
