The process of creating a web application is quite time-consuming and multi-stage. That is why a whole team of specialists with relevant skills is working on it. Each of them performs an important mission and has their own responsibilities.
However, among all these specialists, it is worth highlighting a senior backend developer – a specialist who takes care of creating a functional and reliable technical basis. In this article, we offer to learn in more detail what exactly such a specialist does and to understand their role in the process.
The Foundation of a New Web Application
To understand how valuable these specialists are in the development process, it is enough to analyze the specifics of their activity. Backend developers are those people who deal with all components of the internal part of the software solution. That is, their responsibilities include maintaining the operation of data processing mechanisms, creating a basis for security and signaling (interface interaction), and running various functions on the server side.
All this cannot be seen by the users, but they can evaluate the responsiveness of the buttons, the specifics of performing certain actions in the web application, and other points related to the internal functionality. It is worth noting that the responsibilities of backend developers also include processing and managing large amounts of data. For this, experts create effective solutions for searching and storing data.
Cooperation and Integration
In the process of work, backend specialists actively interact with the teams that develop the interface. They create certain technological solutions that serve as points for data exchange between parties. This is the key to the harmonious development of a software product with minimal risks of errors and bugs. In addition, such points are the basis for real-time updates and smooth interaction.
Protection of Databases
The responsibility of establishing a system for reliable protection of confidential information of users and owners is also assumed by the backend developer. They implement special authorization and authentication mechanisms that allow you to control visits to the web application and protect it from hacking.
Access levels are also implemented. For example, only authorized users can interact with certain components. Another important step towards this is the implementation of special encryption protocols. They guarantee additional protection against unauthorized use of data.
Traffic Scaling and Handling
During the use of each software product, certain waves of activity are observed. There may be peak loads at some hours, and no traffic at all at others. Such fluctuations are harmful to the web application, so there is a need for load regulation. This is also the responsibility of the backend developer.
For this, the specialist usually uses different methods of distributing the load between several servers. In particular, thanks to the introduction of caching mechanisms, as well as balancing technology. In this way, the risks of failures in the web application are significantly minimized, which allows you to avoid large losses from minor failures.
Conclusions
The backend developer is one of the key figures in the process of creating a web application. This is due to the specifics of the work of such a specialist. They handle all internal processes: code creation, security, and functionality setup, creating channels for interaction with frontend developers, as well as scaling and data processing. This means that their skills and knowledge contribute not only to the functionality but also to the efficiency and security of the software solution.
