 ## Module Architecture
 Each service is implemented as a separate maven artifact consisting of a Spring-boot application. Within each project

+we used the principles of `Hexagonal architecture`, where the domain itself consists of only pure Java classes,
 with no technological dependencies. By using such separation, we nicely created an extra separated layer on top of the
