Have you done architecture from scratch or worked with system design?

Yes, experience in designing architecture from scratch and working with system design includes analyzing requirements, selecting technologies, defining system components, and their interactions. It is important to consider scalability, fault tolerance, performance, and security.

For example, when designing a web service in Go, the following layers can be distinguished:

• API layer (handling HTTP requests)
• Business logic
• Data access layer (e.g., working with a database)

It is also worth considering the use of queues, caching, and monitoring to enhance reliability and scalability.
