Describe your last work experience and main responsibilities at your previous job.

At my previous job, I was involved in developing applications in C#. My main responsibilities included:

• Developing and maintaining the application's business logic.
• Working with databases through Entity Framework.
• Creating and optimizing REST APIs.
• Participating in code reviews and writing unit tests.
• Collaborating with the team to discuss requirements and plan tasks.

For example, I implemented functionality for processing orders, where it was necessary to ensure proper data validation and integration with external services.

public class OrderService
{
    public bool ProcessOrder(Order order)
    {
        if (!ValidateOrder(order))
            return false;
        // Order processing logic
        SaveOrder(order);
        return true;
    }

    private bool ValidateOrder(Order order)
    {
        // Order data validation
        return order != null && order.Items.Any();
    }

    private void SaveOrder(Order order)
    {
        // Saving to database
    }
}
