About
Roastmaster means both.
The master is the one who learned the craft. The roaster is the one who knows when to take the beans out. Both are the same work: heat, time and judgement.
I am a Senior Modern Workplace Consultant at amexus and a Microsoft MVP. I build SharePoint, Teams, Entra and Azure landscapes, speak about them in German and English, and write down what goes wrong along the way.
What fifteen years taught me: the tenant is rarely the problem. The translation is.

The pull

seconds.
Too short and it's sour. Too long and it's bitter. Everything lies in between. Just like a rollout.
