Backend Development – Skills&requirements – Directions

Backend developers work with databases, web servers, server scripts, and APIs. These specialists are also responsible for integrating most of the services with your website. It is thanks to backend developers that things such as sharing on social networks, reCAPTCHA, online payment, and the ability to check card balance work. It is in the backend where processes are automated. In general, only a very simple static website can be built without a backend developer.

Skills

What should a backend developer know?

One or more server-side programming languages – this can be PHP, Python, Java, Ruby, or Perl ( Node.js runtime environment is also frequently used)
Database management systems: MongoDB, MySQL, PostgreSQL, etc.
AJAX, the technology for updating data in the browser without reloading the page
Frameworks, to solve project tasks faster and more efficiently – for example, Django ( Python), Rails (Ruby), Laravel (PHP), and Spring (Java)
The basics of the frontend development, to better design applications and interact with frontend developers
The principles of operation of web servers such as Apache, NGINX, and IIS
Version control systems, such as Git, Mercurial, CVS, and SVN

It would be a plus if the specialist understands the principles of UNIX systems and can draw up technical specifications.

The set of skills depends on the tasks. On a small project, it may be sufficient to know PHP (or even Node.js) Ajax and be able to work with a single DBMS. For a large online store, you need a mastery of technologies such as Docker, Kubernetes, experience with high loads, and knowledge of the monitoring systems.
