Hi! I had the same problem, but I did a kimera with his service-rest here(github.com/sebastienblanc/keycloak-quickstarts/tree/master/service-springboot-rest) and the app-spring with this too(github.com/sebastienblanc/keycloak-quickstarts/tree/master/app-springboot). The great tip is adapt those two with what you see in this video :)
I wouldn't mind the speach impediment - it's somehow understandable what he is talking - but I can't handle much more the overall 'I am trying to be so cool, and over-hyped guyz!'-manner - he was trying too much to be funny, but it didn't work and brought more embarrassment rather than understanding of the topic. Next time try to be more 'real' rather than comical.
