Web Developer
A Web developer is someone who creates Web-based applications by using programming languages. Basically, a Web developer makes things "happen" within a Web site or within a single Web page. By making things happen, I mean form-related functions, such as database calls, queries, compilations, scripting include-based (dynamic) templates, or anything that allows the user to interact with elements of the Web site.
If you want to become a Web developer, you need to be familiar with client-side scripting and/or server-side scripting. Additionally, you need to have some familiarity with database creation and maintenance.
A Web developer doesn't usually worry about the presentational aspects of the applications they create beyond the overall user experience. In some cases, Web developers can also be Web designers, enhancing the programmatic output through presentational manipulation. But, usually, after the programmatic scripting is completed, the Web developer's project is then handed off to a Web designer.
Beyond the technical knowledge required, it's beneficial for Web developers to study and understand usability (what makes a successful end-user experience), accessibility (what's needed to accommodate those with disabilities wanting to view your Web site), and W3C standards.
Generally, those with good analytical and logical skills make good Web developers. If you enjoy math, science, problem-solving, or mechanical manipulation, Web development could be for you.
