Two years experience in DevOps, 13 years experience in Linux/Unix systems administration. I transferred about 40 projects from manual deployment with SVN to CI/CD with Git and Jenkins on a closed private data center in Kyiv. I managed to do this without interrupting the work of a project's versions. I created and implemented a scheme for a network of servers remote installation on the XenServer platform on the Hetzner data centers' servers. I created an internal infrastructure for developers from scratch. It was a completely standalone CI/CD projects assembly for Laravel with deployment to shared hosting. I configured a terraform (IAC) description of provisioning a Kubernetes cluster on Google Cloud Platform.
