Қиын жүйелердің архитектурасын жобалауда бұрын жұмыс істедіңіз бе?

Yes, in several projects I participated in designing the architecture of complex systems. This included defining application layers, choosing design patterns such as MVC, CQRS, and implementing SOLID principles to ensure scalability and maintainability of the code. I also worked on integrating with external services and ensuring system fault tolerance through the use of message queues and caching.
