Senior Site Reliability Engineer · Singapore
I am a Senior Site Reliability Engineer based in Singapore with a focus on Linux platforms, bare-metal automation, and global networking (BGP, DNS, CDNs).
Over the past decade at Cloudflare, Adyen, and Thales Cybersecurity, I have engineered systems spanning the entire stack—from UEFI provisioning and bare-metal lifecycle management to distributed storage with CEPH, traffic engineering, and container orchestration with Kubernetes.
Outside of work, I operate my own autonomous system (AS209792), build open-source utilities in Python and Go, and volunteer with Repair Kopitiam diagnosing and fixing consumer electronics.
