Hi, I'm Ardi Sujaya. I keep systems reliable, from the ground up.
From watching dashboards in a Network Operations Center to building and maintaining resilient infrastructure today — I've spent my career making sure systems stay up, incidents stay calm, and operations run smoothly.
Get in touch →A bit about my path
I started out watching over networks and systems in a Network Operations Center, learning to spot problems before they became incidents. That grew into hands-on System Administration, then into Site Reliability Engineering, where uptime and calm incident response became second nature.
Today, as a System Engineer, I focus on building and maintaining infrastructure that just works — combining operational discipline from my NOC roots with the reliability mindset of SRE.
