Tell us about an integration project involving three or more systems that you worked on, how the architecture was arranged, and what role you played.

In one of the integration projects, I participated in a setup involving three systems: CRM, ERP, and an external delivery service. The architecture was built on microservices using REST API for communication between the systems.

My role involved analyzing requirements and designing integration scenarios. I described business processes, identified integration points, and participated in testing data exchange.

For example, when an order was placed in CRM, an order was automatically created in ERP, and then a delivery request was sent to the external service. We used a message queue (RabbitMQ) for asynchronous data transfer and reliability.

This approach ensured data consistency and increased automation of processes between the systems.
