What architecture have you worked with? Describe the architecture of your current project under the hood - how it is arranged, what layers, how domains are separated.

In the current project, the architecture is built on microservices principles with clear separation of domains and layers.

Main layers:

• API layer: Handles incoming HTTP requests, performs validation and routing.
• Service layer: Contains business logic, implements domain rules and processes.
• Repository layer: Responsible for interaction with the database and external storage.

Domains are separated by functionality: for example, separate services for managing users, orders, payments, and notifications. Each service has its own database and API, allowing them to be developed and scaled independently.

Interaction between services occurs via gRPC or REST, and message queues (e.g., Kafka) are used for asynchronous tasks. This approach ensures modularity, ease of maintenance, and scalability.
