What I'm looking for

I seek roles focused on Linux infrastructure, automation and cloud where I can lead migrations, improve reliability, and work in small high-performance teams with opportunities for certification growth.

I am a Linux System Administrator with over eight years of hands-on experience managing critical production environments across RHEL, CentOS, Debian, Rocky Linux and Ubuntu in 24×7, high-availability setups.

I specialise in infrastructure automation using Ansible and Bash, containerisation with Docker and Podman, cloud deployments on AWS and Azure, and Red Hat migrations with Infrastructure-as-Code practices.

My work includes web and application server management (Apache, Nginx, Tomcat), vulnerability and CVE remediation, ISO 27001-compliant operations, and on-call 24×7 incident response with strong documentation practices.

I am proactive, autonomous and experienced in small high-performance teams; I hold LPIC-1 and am preparing LPIC-2, continually expanding skills through formal training and practical projects.
