Linux Systems Administrator/Engineer securing enterprise and cloud infrastructures with automation and compliance.
What I'm looking for
I am a Linux Systems Administrator/Engineer with 5+ years of hands-on experience supporting, hardening, and troubleshooting enterprise, government, and cloud Linux infrastructures. I specialize in RHEL, Ubuntu, CentOS, Rocky, and SUSE, and I bring practical automation expertise with Ansible, Bash, Python, and Terraform to streamline operations and reduce downtime.
My background includes managing hundreds of production servers across hybrid on-premises and cloud platforms (Azure, AWS, GCP), building high-availability clusters for POS and e-commerce systems, and embedding compliance controls (DISA STIGs, CIS Benchmarks, NIST 800-53) into automation pipelines to improve audit outcomes. I have delivered measurable results such as cutting downtime by 40%, reducing recurring incidents by 25%, and closing 90%+ high-risk vulnerabilities in collaboration with SOC teams.
I am proactive, documentation-driven, and mentor junior staff while participating in 24x7 rotations and Tier 2/3 escalations. I seek to apply my Linux, cloud, and security skills to help a growing organization scale securely and maintain resilient, compliant infrastructure.
