Serhii Alieksieiev

I’m a DevOps engineer and system administrator with over 14 years of experience administering big remote networks for numerous startups and projects—locally and remotely. Since 2015, I’ve provided DevOps support to multiple developer teams across different initiatives, keeping a self-motivated, detail-oriented, multi-task mindset. I’m fluent in Ukrainian, Russian, and English, and I focus on clear, reliable communication with teams.

My core strength is end-to-end Azure infrastructure management and secure CI/CD: I deploy and manage environments with Terraform (and Azure Bicep less), provision with Packer, and build/test/deploy with Jenkins while embedding DevSecOps tools into pipeline steps. I implement security and backup policies for critical services using Azure IAM, Azure Key Vault, least-privilege access, static application security testing, container image scanners, and blackbox testing—then monitor everything with Grafana + Prometheus + Loki + Alertmanager (plus Azure Metrics/Log Analytics where needed). I support Windows and Linux administration, use PowerShell and Bash for automation, and work with Docker, KVM (and earlier VMware), and nested virtualization to keep systems dependable under real operational constraints.
