I build AI the way security people think.

I treat model output as untrusted input. It’s the through-line in most of what I’ve built. Cyber Cookie publishes an AI and cybersecurity digest unattended, feeding scraped web content to agents behind delimiters and a review gate. In Sentry, an agent reads the conversation and a deterministic check engine makes the call.

Every pipeline I build ends at a gate that plain code or a person controls.

I’m a final-year Computer Science student at NUS specialising in AI and Cybersecurity, graduating December 2026. Before this I spent eight months in Singapore Airlines’ GRC team, building AI tools into security workflows people now use.

Away from the keyboard I climb, emcee events, and used to command a platoon.

I like saying yes to challenges. It’s how I ended up emceeing award nights and launches, and why I keep going back to rock faces and mountain trails. And when my schools needed someone to represent them, at open houses, homecomings and career fairs, I put my hand up.
