In the previous article, we discussed that web development has two parts the frontend and the backend, that when working together we obtain the development of a digital product called a web application. Now let’s delve a little deeper into the concept of the backend and the main functions of a backend developer.
The backend is the part of web development that deals with the logic of a website that allows everything to work properly. A concept that refers to all server-side development or any logic system that the end-user cannot see, for example, handling user input data, executing scripts, and connecting to APIs.
The backend developer is one of the most necessary roles to build customized digital products, as they will be in charge of programming the business logic and at the same time work in synergy with the frontend development team to deliver an integral, functional, and valuable web app. The main responsibilities of a backend developer are:
- Build the logical systems of all the website features
- Maintain all the resources and libraries required by the project up to date
- Design the database structure to store the data properly
- Maintain the web application with reduced latency
- Serve the information and resources required by the frontend
- Maintain all components of the website secure
Important skills
Backend developers are in high demand in the world. Therefore, in addition to mastering backend programming languages such as Javascript, Golang, or Python, which in turn implies knowing the most popular frameworks in the selected language, they must also possess essential skills to be taken into account in some of the job offers.
Data structures and algorithms: Having knowledge of data structures and algorithms will allow you to deal with database and information management.
Basic server management: Considering that all development occurs on the server-side, it is important that the programmer also knows how to handle the terminal and has the basic knowledge to work with virtual machines and servers in general.
Git: It is the most popular open-source version control tool, if not the only one that most companies use for version management. So it is very important to master this skill.
