That we got a complex overview also about the context - for example why do we need some annotations and what they mean. I liked the practical part of the training - having to manually run the commands and call the rest api's
Alina - ACCENTURE SERVICES S.R.L
Course - Quarkus for Developers
The extra information that was shared, the training was not straightforward groovy, which was nice.
Covenant - Vodacom
Course - Groovy Programming
the trainer can clearly explain the topic and can answer every question.
Hannah Mae Lubigan - Security Bank Corporation
Course - Advanced Spring Boot
Training style and trainer helps solve issues encountered during the exercises.
Carl Angelo Gonzales - Security Bank Corporation
Course - Spring Boot for Beginners
The breadth of the topis covered was quite a bit and the trainer tried to do justice to that.
