Do you have practical experience in developing architectural solutions for complex systems?

Yes, within Go projects I have experience developing architectural solutions for complex systems. This included:

• Designing modular structures with clear separation of responsibilities between components.
• Using design patterns such as Dependency Injection, Repository, and Event-driven architecture.
• Organizing interactions between services via gRPC or REST API.
• Ensuring scalability and fault tolerance through microservices and containerization (Docker, Kubernetes).
• Implementing error handling, logging, and monitoring mechanisms.

For example, in one project, I designed a system for processing large data streams, where channels and goroutines were used for parallel processing, and the architecture allowed easy addition of new data sources and handlers without changing the core system.
