I am a long time user of Hashicorp Packer and Terraform. I am also an open-source contributor to various Terraform & AWS projects, terraform-aws-modules, modules.tf and a few others. The most popular one is where I manage a collection of verified Terraform AWS modules (terraform-aws-modules on GitHub) which is being downloaded more than 850K times each month.
I also lead AWS and HashiCorp User Groups in Norway, organize DevOpsDays Oslo, and speak often at various technical meetups and conferences.
