Summary
🤩
Rockstar🎓
Top SchoolNathan Metcalf is a Site Reliability Engineer based in Melbourne with four years of focused SRE and Linux operations experience and a decade-plus background in IT support and system administration. He has built resilient, high-availability systems—from BGP-backed co-location failover and custom Bash automation to VMware host redundancy and VLAN/802.1x network segregation for schools—balancing reliability with practical maintainability. At Expensify he continues to support diverse Linux servers and applications while running NDM.guru, where he applies hands-on hardware and embedded skills to real-world problems (including rebuilding a tractor gearbox controller with a microcontroller). Comfortable spanning the stack, Nathan is driven more by solving the root problem than by technology for its own sake, bringing a pragmatic, inventive approach to operational challenges.
