About Me

I'm a Junior Systems Engineer and final-year Computer Science student based in Brisbane, QLD. I blend theoretical knowledge with real-world experience through innovative projects and hands-on work.

At Adfinis IT Australia, I provision and maintain Linux server infrastructure for customers worldwide, automate workflows with Ansible and Bash, and support CI/CD pipeline improvements. I'm passionate about infrastructure-as-code, cloud automation, and open-source technologies.

Currently pursuing my Certified Kubernetes Administrator (CKA) certification and Azure Fundamentals (AZ-900) to deepen my expertise in container orchestration and cloud platforms.
