Current work
As Principal IT Architect in the School of Computing (SoC) at the National University of Singapore, I am responsible for a broad portfolio of IT infrastructure services. I lead a cross-functional team of engineers and technicians.
SoC is unique in being the only faculty in the university that operates its own IT infrastructure. We are hands-on and run our services in-house, without outsourcing technical functions. My work also spans data-centre facilities, procurement, technical consultation and ad-hoc projects, including national and international IT events.
We operate three data centres across Kent Ridge Campus, providing geographical separation for localised disaster isolation. Facilities monitoring supports remote diagnosis and assessment, while high-density compute servers run at up to 20 kW per rack.
Our IT infrastructure services span a large and complex wired and wireless network, firewalls, application load balancers, Linux servers, virtualisation platforms and resilient storage. We operate a large high-performance computing cluster using the Slurm workload manager, alongside SAN storage clusters and Ceph on commodity x86 servers.
My current work also involves substantial AI services. I developed an LLM API gateway SoCLaaS (SoC LLM-as-a-Service) to provide free and virtually unlimited LLM API access to SoC students to support their learning and self-exploration.
Awards and certifications
I received the Commendation Medal at the National Day Awards in 2009. I have been a Certified Information Systems Security Professional (CISSP) member since 2003.
Past work
Before joining the School of Computing, I was a Research Officer at the Internet Research and Development Unit, also part of the National University of Singapore. My work focused on advanced research and education networks, primarily with the Singapore Advanced Research and Education Network (SingAREN).
