I am a ServiceNow developer. I build catalog automation, flows and integrations for clients, and I usually end up recording the handover training for the team that inherits the work. That training is where my courses come from, which means everything I teach is something a business actually paid to have built.
I teach the way I work. Unscripted, on a live instance, mistakes left in. When something breaks on camera I debug it rather than cutting it out, because working out why a build is broken is most of the job and it is the part tutorials usually skip.
If you get stuck on anything in my courses, use the Q and A. I read it.
