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.

My code is on GitHub and my career history on LinkedIn.

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 with AI-assisted development.
