What are Backends?
The backend is the part of a system or application that is not visible to the user, but is responsible for handling application logic and communication with other systems. In general, the backend consists of three main components: server, application, and database.
In general, the backend is responsible for handling application logic, processing data, and handling communication with other systems. The backend is also responsible for handling authentication and authorization, which is the process of identifying users and granting access rights according to their security level. The backend can also handle data management, such as storing, modifying, and deleting data from the database.
Some of the technologies used in backend development include:
- Web frameworks such as Express.js (for Node.js), Ruby on Rails (for Ruby), and Django (for Python).
- Databases like MySQL, PostgreSQL, MongoDB, and Cassandra.
- Communication protocols such as REST or GraphQL.
What are the Backend Developer Job Roles?
As we know before, backend developer jobs or backend developer jobs are one of the important roles in application or website development. This is the part of the application that is not visible to the user, but is very important in governing how the application or website functions. The following are some backend developer job roles that you should know about:
1. Handle Communication Between Application And Database
One of the main roles of a backend job is to handle the communication between the application and the database. Backend workers must be able to write efficient code to retrieve, add, update, and delete data from the database. This requires knowledge of databases, such as SQL, and knowledge of programming, such as Python or Java.
2. Handling Requests From Applications
In addition, the backend worker must also be able to handle requests from the application and return appropriate responses. This requires knowledge of network protocols, such as HTTP, and knowledge of programming, such as Node.js or Ruby on Rails.
3. Designing Website/Application Flow
The role of the next backend developer job is to ensure users can experience a good user experience. The trick is to design an easy and efficient software usage flow. To design this software flow, the backend developer must have high coding and programming logic skills.
4. API Development
The next backend developer job is to be able to develop an API (Application Programming Interface) that is used by the frontend to interact with the backend. The API allows applications to fetch data from databases or external systems and display it to users.
The backend must write efficient and secure code to ensure that the data received by the application is valid and cannot be altered by unauthorized parties.
5. Maintain Application Security
In addition, backend workers must keep the application safe and protected from attacks that may come from outside. This requires knowledge of network security and ways to prevent attacks, such as encryption and authentication.
6. Optimizing Application Performance
In addition to the roles mentioned earlier, backend workers must also be able to manage and optimize application performance. This can include tasks such as optimizing database queries, optimizing code, and managing application scalability. Backend workers must be able to identify and address performance issues that may arise during application development and production.
7. Manage Application Infrastructure
Backend workers must also be able to manage the infrastructure used by the application. This can include tasks such as managing servers, managing application installations, and managing networks. Backend workers must be able to identify and address infrastructure issues that may arise during application development and production.
8. Overcoming Problems That Appear on the Backend
Backend developers must be able to maintain the application and address issues that arise during development and production. Therefore, the backend developer has a duty to do troubleshooting. Problems must be found and then fixed so that the error does not reappear.
9. Code Maintenance And Updates
Backend developers must be able to maintain code in a way that follows established code standards and identify and address issues that may arise.
In addition to maintaining the code, the backend developer must also make necessary updates to maintain compatibility and security in the application.
10. Create Documentation
In addition to performing code maintenance, backend developers must be able to compile clear and detailed documentation to explain how the application works and how to solve problems that may arise.
