I manage secure Red Hat Linux infrastructure, automate compliance, and lead server migrations.

What I'm looking for

I'm seeking to apply my Linux administration, system security monitoring, auditing, automation, and infrastructure experience to help achieve enterprise-wide system security goals and objectives.

At Nextgen Data Cloud, I install, configure, patch, secure, and troubleshoot Red Hat Enterprise Linux servers while supporting virtual and physical infrastructure.

I automate projects and security hardening with Ansible, Bash, and Python, including DISA STIG compliance assessments, remediation, access controls, and reporting. I also coordinate Linux migrations, NFS deployments, VMware activities, and datacenter projects with application, network, storage, security, and infrastructure teams.

Previously at Ubeet Technologies, I managed more than 50 Linux servers, automated updates and patches, and implemented Nagios monitoring to improve incident response. I supported backups, disaster recovery, CI/CD deployments, DNS, DHCP, VPN services, and legacy-to-Linux migrations.

I bring hands-on Linux administration, security monitoring, auditing, automation, and server support experience backed by RHCSA, CKA, CompTIA Security+, Linux+, CCNA, AWS Solutions Architect Associate, and Oracle/Solaris certifications.
