Have you participated in designing the architecture of a software product?

Yes, I have participated in designing the architecture of software products. This usually includes:

• Requirements analysis and task setting.
• Choosing technologies and tools suitable for solving the problem.
• Defining the main components of the system and their interactions.
• Designing data structures and APIs.
• Considering scalability, fault tolerance, and security.

For example, when developing a web application, I helped define the architecture layers (frontend, backend, database), select REST API for interaction between components, and design the database with future load growth in mind.
