Have you been able to participate in developing architectural solutions for projects?

Yes, I participated in developing architectural solutions for projects. This usually involves analyzing requirements, selecting design patterns and technologies, as well as creating a modular and scalable application structure. For example, when developing in C#, I used a layered architecture with separation into data, business logic, and presentation layers, which facilitated maintenance and testing of the code.

// Example of a simple architecture using interfaces
public interface IRepository<T> {
    IEnumerable<T> GetAll();
    void Add(T item);
}

public class UserRepository : IRepository<User> {
    public IEnumerable<User> GetAll() {
        // data access implementation
    }
    public void Add(User user) {
        // add user
    }
}

public class UserService {
    private readonly IRepository<User> _repository;
    public UserService(IRepository<User> repository) {
        _repository = repository;
    }
    public void RegisterUser(User user) {
        // registration business logic
        _repository.Add(user);
    }
}
