Back-end Web Developers are responsible for server-side web application and integration of the work front-end web developers do. They will write web services and APIs used by front-end developers. Working closely with marketing and design functions they will use test sites to see which ideas best suit the brief.
Using reliable code, they will build the framework considering UI, cross-browser compatibility, general web functions and standards.
A Web Developer will need a good understanding of server-side CSS preprocessors, accessibility and security compliance as well as authentication between multiple systems and servers.
With the growing use of tablets and smartphones, it is essential for a Web Developer to understand the differences between mobile vs desktop platforms.
Sheffield is located in the metropolitan borough of South Yorkshire; its name is derived from the River Sheaf, which runs through the centre. The city sits within the valleys of the River Don and its four tributaries: Loxley, Porter Brook, Rivelin and the Sheaf. Over 60% of Sheffield's entire area is green space and a third of the city itself lies within the Peak District national park. Boasting more than 250 parks, woodlands and gardens, the city is also proud of its historic sports scene, being home to the world's oldest football club, Sheffield Football Club. During the 19th century, Sheffield gained an international reputation for steel production. Many innovations such as stainless steel were developed locally, almost single-handedly fuelling the Industrial Revolution of the UK. International competition in iron and steel created a decline in the traditional industry during the 1970s and 1980s, coinciding with the collapse of coal mining. Today it's not the steel of the foundries, mills and forges that make the city's fortune but the scaffolding, cranes, modern sculptures and steel-framed buildings that stud the skyline. Thanks to opportunities of urban renewal, Sheffield is working hard to reinvent itself. The modern economy is based on services, shopping and the 'knowledge industry' flowing from the University of Sheffield and Sheffield Hallam University.
