What I'm looking for

I'm looking to apply my RHEL administration, automation, security hardening, and Tier-2/Tier-3 troubleshooting experience to reliable enterprise infrastructure and complex technical operations.

I've supported enterprise Linux environments at Copart Inc, resolving 100+ monthly Tier-2/Tier-3 issues across system configuration, access, services, and infrastructure operations.

I strengthened RHEL security through SELinux policies, firewall rules, SSH hardening, and access controls, reducing unauthorized access attempts by 85%. I also helped reduce average incident resolution time from 24 hours to 8 hours through improved troubleshooting and escalation processes.

At Cognizant, I automated distributed system administration with Ansible, deployed multi-node RHEL labs, and improved client-compliance documentation accuracy by 25%. I'm RHCSA and RHCE certified and bring hands-on experience with RHEL administration, LVM, networking, Kubernetes, Docker/Podman, and Azure fundamentals.
