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.
Developing an upcoming cybersecurity product. Implemented network anomaly detection using VictoriaMetrics Anomaly. Automated Blue/Green deployments for imperva.com using Argo Rollouts, latency monitoring, and infrastructure reliability.
Managed external DNS architecture, CDNs, edge load balancing, and Linux automation at scale.
Bare-metal server provisioning, UEFI automation, hardware validation standards, data center tooling in Django, and edge network operations.
Operated high-volume NNTP storage platforms with petabytes of storage and terabits of network traffic.
Engineered scalable data platform infrastructure for rapid startup growth.
After renewing my MyRepublic fiber contract, they didn't want the old Nokia G-240G-E ONT back. Naturally, I wrote a custom bootloader, ported mainline Linux 7.4-rc1, and turned its 13 front-panel LEDs into a button-toggled light show.
How I built a lightweight Rust daemon that interoperates with SP Digital's OAuth2 + SMS MFA flow and brings half-hourly AMI electricity, water, and gas telemetry into Home Assistant's Energy Dashboard.
