Hi! I work on building and protecting trust in an increasingly digital world. I started my career working on Singpass, Singapore's national digital identity. Currently researching agentic AI authorisation and delegation.

Selected work

Singpass Authentication
Singpass · GovTech Singapore
Engineered the rebuild of Singpass' Core Authentication products as part of the in‑house Authentication team. Designed, tested, launched, and transparently migrated relying parties to a brand‑new OIDC‑compliant Singpass Authentication system — downtime‑free, within ten months.

About

get to know me

I first dabbled with hardware as a 10-year-old and became the go-to person for my friends and family to fix their tech woes. It wasn't until my early twenties that my journey in software began.

I've had the privilege of working on Singapore's national digital identity, Singpass, building products in the digital identity space — a key pillar of digital public infrastructures. Currently, I'm researching about Agentic AI access controls, delegation, principal authorisation and auditability.

I'm a software engineer by profession; also a creative, writer, and service-design enthusiast — dedicated to co-creating user-centred and interoperable digital public infrastructures as a force for good in an increasingly digital world.

Guiding principles
01To always consider the ethical implications and consequences of the technologies I'm working on.
02To remain open to revising my beliefs and philosophies when presented with compelling opposing views supported by substantial evidence and peer-reviewed insights.
03To do my best with the absolute most fun – that also means being experimental with a child-like curiosity and wondering demeanour.
