I am an IBM employee (Linux Developer) at IBM since this month. This week I have received the approval to contribute to openSUSE Packaging for Z. Additionally, I am open to communicate Z specific topics to our company for our team.
Before I had studied Computer Science in Nuremberg and wrote my Bachelor Thesis at IBM. I will switch from the Translation Team to the Z Systems Team at openSUSE now. I was allowed to see many failed packages for Tumbleweed. So I can see how I can help you here.
Best regards, Sarah
