Nenad Nenad
Senior Software Developer I BLS AG
Even though our company is already highly product-oriented, "DDD, EventStorming and CleanCode" course has provided us with valuable tools to take our approach to the next level, by ensuring that our technical models truly reflect the core domain.
Lucas Lucas
Engineering Manager, Migros Online
The course was a good introduction to Microservices with Spring Boot. We can now start discussing how we want to build up our microservice structure and whether it is necessary to destructure existing monoliths
