About
I'm a Senior Site Reliability Engineer at Apple Services in Singapore. For more than nine years I've run production Linux, cloud and Kubernetes systems, and I treat operations as a software problem: automation, infrastructure as code and reliability you can measure.
I came to this work sideways. I trained as a mechanical engineer and started out maintaining heavy machinery at an iron ore mine. Linux had been my daily system since college, and after running a small education startup I rebuilt a research institute's infrastructure from a decommissioned HPC cluster. Site reliability engineering grew from there.
Outside work I keep a small Kubernetes cluster at home to try out platform ideas. This site runs on it.
Experience
Apple — Senior Site Reliability Engineer, Apple Services
Singapore · 2023 – present
Designed and built an internal platform, in Python on Apache CloudStack, that manages the full lifecycle of virtual machines declaratively behind a modern API: provisioning, application deployment, reimaging and migration of legacy applications. Teams across Apple Services use it.
Automated fleet-wide security patching: machines are reimaged whenever a new hardened image is released, with no manual patching.
Run production services with my team across AWS, Kubernetes and physical infrastructure, from deployments and capacity planning to disaster recovery.
Lead on-call incident response for customer-facing services.
Build internal tools in Python and Shell, often with Claude Code.
