DevOps Architect
My primary goals are to create, adjust and apply the best practices
for the Environments, applications and networks. This includes the
creation of the architecture, to set the deployment processes, to
implement the proper monitoring with the alerts and last but not least
to implement a security. And all of this should be IAC (Infrastructure
as code) and fully automated. Usually I’m using the DevOps tools
like Ansible, Terraform, Jenkins, GitLab Git. Etc.. Of course there
are more tools and even created custom ones with script languages.
