Professional summary

More than 14 years of experience in IT, network administration and infrastructure analysis, mostly on GNU/Linux environments. Since 2015 I have worked with infrastructure automation (Infrastructure as Code) using a range of tools for different scenarios — from immutable provisioning to cloud platform operation pipelines (AWS, Kubernetes/EKS, Terraform, Ansible, GitLab CI).
