Tell about your practical projects and experience in the commercial sphere.

This question involves sharing your personal experience, so I will provide an example of how to structure your answer.

In commercial development, I participated in creating web applications using C# with ASP.NET Core. For example, I worked on a CRM system project, where I was responsible for implementing business logic and integrating with the database via Entity Framework.

I also have experience developing REST APIs, writing unit tests using xUnit, and optimizing application performance.

In projects, I used design patterns such as Repository and Dependency Injection, which improved code maintainability and scalability.

When discussing specific projects, it is important to mention:

• The goals of the project and your role
• Technologies and tools used
• Tasks solved and results achieved

For example: "In an online store development project, I implemented an order management module, ensuring correct transaction processing and integration with payment systems. This helped increase the reliability and speed of order processing."
