Web Developer


    Web developers build, and make improvements to, websites and web applications.  Although their work usually focuses solely on the underlying software and databases (known as the ‘back end’), some web developers work on the interface and visual design (the ‘front end’), while others combine both (‘full-stack development’).

    In an agency or as a freelancer, a web developer’s job is to create products that meet clients’ needs. The work can be particularly varied with many projects to work on simultaneously and lots of meetings with clients to discuss their requirements and update them on progress.

    In all cases a web developer’s primary task is creating reliable and high performing applications and services, which can be accessed over the internet.
