Proper creation of API (Application Programming Interface) provides communication between the server and the client part, as well as with other services . REST and GraphQL are popular approaches to API development.
The backend developer must pay great attention to data security and user authentication. Implementing such measures as encryption, using HTTPS, applying JSON Web Tokens (JWT) helps to ensure the privacy of user data.
Modern systems often use microservices architecture instead of a monolithic approach to achieve high scalability and ease of deployment.
** Testing **
Testing is an integral part of development. Writing unit tests, integration benin mobile phone number list tests, and performance testing are the key to a high-quality and reliable project.
**Deployment and Maintenance**
Deployment and continuous maintenance of the system's operability are also the backend developer's responsibilities. For this, platforms and tools for continuous integration and deployment (CI/CD) are used, such as Jenkins, GitLab CI, Docker, Kubernetes.
Good documentation is important not only for external API users, but also for the development team. The back-end developer should be able to effectively document their code and the architecture they are creating.
Backend development requires a comprehensive approach that includes not only programming, but also knowledge of security, networking, database management, and system operations. A modern backend developer is a multi-disciplinary specialist who can solve multi-level problems to create reliable and scalable web systems.
