A Back-End Developer is a type of computer programmer who integrates server-side web application logic with the work front-end web developers do. They ensure that the data or services requested by the front-end system or software are delivered through programmatic means. In short, they develop applications that are never visible to the user.
A Back-End Developer is computer programmer responsible for creating the logical back-end and core computational logic of a website, software or information system. Think of any operation on your website like sending a contact form, signing up for a newsletter or editing page content, it is always a back-end code responsible for that operation. Furthermore, a Back-End Developer performs the testing and debugging of any back-end application or system.
Aside from having a degree in computer programing or a course relative to programming, database expertise is a must-have skill in hiring a Back-End Developer. Combining these two amounts to a competent and savvy Back-End Developer. Outsourcing companies can help you find the best man for the job. They screen candidates carefully in order to provide you with an employee that's both vastly knowledgeable in the field and has a dedicated approach to work.
The cost of a Back-End Developer not only depends on his educational level and working experience but on his skill level as well. Presenting accomplished projects adds to a Back-End Developer’s value, thereby adding more probability of a better rate.
