Linux Administrator focused on production Linux systems, Bash automation, Ansible, monitoring, server hardening, and reliable infrastructure operations.
I am a Linux Administrator and DevOps automation enthusiast with hands-on experience in managing, troubleshooting, securing, and automating Linux infrastructure.
My work mainly focuses on building practical solutions for server operations, monitoring, automation, hardening, backup workflows, and production support. I enjoy creating clean Bash scripts, reusable Ansible playbooks, monitoring checks, and operational tools that make Linux infrastructure easier to manage at scale.
I work across environments based on RHEL, Rocky Linux, CentOS, Ubuntu, and other Linux distributions.
