Web DeveloperA web developer is a programmer who specializes in, or is specifically engaged in, the development of World Wide Web applications, or applications that are run over HTTP from a web server to a web browser. Web developers are found working in various types of organizations, including large corporations and governments, small and medium - sized companies, or alone as freelancers. Some web developers work for one organization as a permanent full-time employee, while others may work as independent consultants, or as contractors for an employment agency. Web developers typically handle both server-side and front-end logic. This usually involves implementing all the visual elements that users see and use in the web application, as well as all the web services and APIs that are necessary to power the front-end. Salaries vary depending on the type of development work, location, and level of seniority.
