Have you ever had to make architectural decisions on your own?

Yes, I have had to make architectural decisions independently, especially in projects with high load and fault tolerance requirements. For example, when developing a service in Go, I chose approaches to scaling, the choice between monolith and microservices, and defined caching and load balancing strategies.

An example of an architectural decision:

• Choosing the CQRS pattern to separate read and write operations to improve performance.
• Using gRPC for efficient communication between services.
• Implementing a circuit breaker to enhance resilience against external service failures.

Such decisions were made based on analysis of requirements, constraints, and the team's experience.
