@andrewferdinandus
Linux Infrastructure Engineer building RHEL patching and compliance automation with Red Hat Satellite and Ansible.
New ZealandWhat I'm looking for
In my independent infrastructure projects, I built and administered a Red Hat Satellite 6.19 environment for errata-based patching, CVE fixes, and Leapp upgrades. I automated host registration and rolling patching with Ansible.
At CodeGen International (Pvt) Ltd, I kept RHEL and CentOS systems stable and secure in 24x7 production. I led a project-by-project migration from Citrix XenServer to VMware ESXi with zero data loss and minimal downtime.
I also implemented ISO 27001 controls, automated infrastructure backups with Rundeck, and hardened RHEL servers against PCI-DSS in my independent projects. I'm committed to secure, reliable, well-documented infrastructure and automating repetitive work where it adds value.
