MAHAMMAD RAFI IBRAHIMCuriosity is my default setting.
02 / ABOUT

A systems mindset.
A human approach.

I’m Rafi — a Linux Administrator with a passion for the infrastructure that makes technology work. From troubleshooting a stubborn system to exploring cloud architectures, I’m drawn to understanding how things connect.

With 7+ years of experience across Khalifa University and IBM India, my work spans enterprise Linux, AWS cloud support, automation and L2/L3 infrastructure troubleshooting. I’m continuing to build on that foundation through Kubernetes and AWS certification study.
