About Me
Hey, I’m Jayden
I’m a Software Engineer at Atlassian in Melbourne, working on the platform that handles service-to-service communication across Atlassian’s microservices. Before that I was an SRE at NAB and a sysadmin at ICE (NYSE), so I’ve gone from managing thousands of physical servers to debugging Envoy proxy bugs and debugging Kubernetes networking issues.
My background is broad, I’ve worked across the full stack, from bare metal and hypervisors through to networking, cloud infrastructure, and application development. That range means I can follow a problem wherever it leads, whether it’s a networking bug, a slow SQL query, or a misbehaving Kubernetes controller. Performance work is something I genuinely enjoy. I like digging into why something is slow, understanding it properly, then actually fixing it. Some of the most satisfying work I’ve done has come from squeezing real gains out of systems that everyone had written off as just being slow.
Outside of work I run a homelab that’s grown from a couple of VMs into a proper rack with BGP routing, IPSec VPN, IaC, and a Kubernetes cluster. I use it to learn things properly, not just read about them. I also do CTFs when I get the time, mostly focused on reverse engineering and exploitation, and write up the interesting ones here.
