Can you describe the architecture of the system you used in your previous position?

In my previous position, I worked with the architecture of a multi-layered application in C#. The main layers included:

• Presentation Layer — responsible for user interaction, implemented using WPF/WinForms or ASP.NET.
• Business Logic — contains core rules and processes, implemented as services and classes.
• Data Access — the layer that interacts with the database through ORM (e.g., Entity Framework).

Interfaces and patterns such as Dependency Injection were used for communication between layers, ensuring loose coupling and ease of testing. Asynchronous methods were also employed to improve application responsiveness.

Some projects utilized a microservices architecture with REST API for inter-service communication.
