Have you been involved in backend development? If yes, what exactly did you do?

Yes, I worked on backend development. Specifically, I implemented REST APIs for database interaction, wrote business logic on the server side, optimized queries, and ensured security through authentication and authorization.

Examples of tasks:

• Creating endpoints for CRUD operations.
• Processing and validating incoming data.
• Integrating with external services.
• Writing unit tests for server logic.

This helped me better understand the interaction between frontend and backend, as well as the features of building scalable and reliable server applications.
