Have you had experience designing architectural solutions for systems?

Yes, within iOS projects, I participated in designing architectural solutions, including the selection and adaptation of architectural patterns such as MVC, MVVM, and VIPER. For example, for a large application, I proposed using MVVM with Combine for reactive data binding, which helped improve testability and separation of concerns between layers. It is important to consider scalability, support, and maintainability when choosing an architecture.
