Deep expertise in Linux system administration (kernel tuning, storage management, sudoers policy), strong proficiency in Ansible (playbooks, roles, Jinja2 templating, dynamic task dispatch) orchestrated through Ansible, and solid scripting skills in Bash, Python, and SQL. Demonstrated ability to implement Infrastructure as Code across the full server lifecycle - OS hardening, storage provisioning via REST APIs, credential injection and fleet-wide configuration enforcement - all driven by version-controlled Ansible with no hardcoded secrets.
