Back-end refers to server-side development. This is a programmer who is responsible for the internal layout of the site (software, applications) and its internal logic. That is something a regular user doesn't see when using the site. But this is the basis without which the work of a front-end developer is simply impossible. They focus on databases, scripts, and website architecture. They contains behind-the-scenes actions that occur when performing any action on the website. This can be logging in to an account or making a purchase in an online store. Code written by back-end developers helps browsers interact with database information.
The most common example of back-end programming is when one reads a blog article. Fonts, colors, designs, etc. make up the front of the page. While the content of the article is rendered from the server and retrieved from the database. That's the internal part of the application.
To put it simply and clearly, the blood and the brain are the back-end, and the face and the looks are the front-end.
Generally, of course, a back-end developer must have the skills to implement algorithms and solve system problems. The job of a back-end developer is to understand the goals of the website and come up with effective solutions. Another important task is data storage, as well as making sure that it is displayed to the user that is supposed to have access to it.
Designing a payment processing system for receiving data, storing that information securely, and charging for the payment. Managing API resources that run on different devices. They may be involved in the system architecture and data analysis. Developers are responsible for organizing the logic of the system that runs across different devices.
A back-end developer should also be involved in creating frameworks or architectures to facilitate programming.
Among the necessary skills, one could mention:
- Web development languages (such as Java, Python, Ruby, .Net, etc.);
- Database and cache (Knowledge of various DBMS technologies is one of the important skills. MySQL, MongoDB, Oracle, SQL Server, and Redis are widely used for this purpose. Knowledge of caching mechanisms, such as varnish, Memcached, Redis, is a plus);
- Server (Impact on the processing of Apache, Nginx, IIS, Microsoft IIS servers is desirable. A good background in Linux helps a lot in server administration);
- API (REST & SOAP) (Knowledge of web services or APIs is also important for full-stack developers. Knowledge of the creation and consumption of REST and SOAP services is desirable);
- Knowledge of front-end basics.
In general, the knowledge of a back-end developer can be divided as follows, depending on their level:
The average salary of a back-end developer in Belarus ranges from $900 to $3,500. But one should understand that the figure will depend on the experience and skills of the developer. In our experience, there were also cases when the client was ready to agree on the salary suggested by the candidate, if, of course, the latter was up to par.
The average salary of a back-end developer in Russia ranges from $700 to $3,000. The salary of an intern will be about 40,000 Russian rubles, a Junior specialist -- about 60,000 Russian rubles, a Middle developer -- 100,000 Russian rubles, a Senior developer -- 180,000 Russian rubles, and a Lead -- 250,000 Russian rubles.
For any programmer (and back-end developers are no exception), knowledge of English is already a requirement, and, as a rule, with a technical bias. To date, it is very difficult to progress in the field of programming without knowledge of English, so, as a rule, we try to recruit developers with a level of English not lower than upper-intermediate. If the client does not need a developer with knowledge of English (and this does happen), we can very quickly help find a developer without knowledge of a foreign language.
There are many opportunities for obtaining education in the field of back-end development: such as various schools, online courses. Very often in practice, we meet guys who initially learned back-end development on their own (and this is not uncommon). Various IT companies conduct their own courses on back-end development, after which, if successful, candidates are offered a job in these companies.
In practice, it is often much more difficult to become a back-end developer than a front-end developer, because back-end developers often need to have a mathematical/physical education in order to better understand algorithms, functions, and patterns. Again, it is best to study on a real project, because it is in it that one will truly understand what back-end really is.
