Meanwhile, the other developer might focus on the interaction between server-side frameworks, the web server, and a database system. Further, depending on the size of their organization, the aforementioned developers might work closely with a content creator/copy writer, marketing adviser, user experience designer, web designer, web producer, project manager, software architect, or database administrator - or they may be responsible for such tasks as web design and project management themselves.
