Project overview
The client uses various tools to reach their customers, such as a mobile app, a responsive web application, or communicating with them directly through the call center.

Our client is committed to ensuring that the system will be as modern as possible. It is based on microservice architecture with the use of continuous integration, where a few hundred components operate independently of each other and can be used as they become available.
