Building chef on LinuxONE/LoZ

I posted the following question on slack channel too, I'm looking for chef contact who in charge of building chef on LoZ.

Hi, I've work with Scott and Jaymala a while back to enable chef build on z linux. I provided some free z VMs access from our community cloud and building ok ever since. Our community cloud team has to upgrade their z hardware and new VMs will be provided. I've been emailing Scott & Jaymala but didn't get any response, not sure whether they're still in the same role. Any pointers are welcome.
