Web development is a loose term that encompasses several services. An experienced developer could oversee building a simple, static landing page or managing the construction of an entire, complex web system. It doesn’t stop at websites, though. A professional website developer could work on internet applications, social network services, and ecommerce business solutions.
These services may also include backend website coding (turning a website design into a working site), creating a custom system to address specific needs, and building a system that manages the content of a site or database.
