I'm Gavin Nguyen. I'm based in Sydney, Australia.
I build payment technology
and research reliable AI.
Co-founder & CTO at Hello Clever
PhD researcher in AI at RMIT University
I co-founded Hello Clever with my business partner and built the technology behind its growth to more than A$70M in annual revenue by August 2026. Today, I'm building it into the exchange layer for global money movement. I research reliable AI, focusing on trustworthy language model behaviour. In both, I care about one thing: building technology people can trust.
- I buildPayments are infrastructure, but people experience them as moments of trust. I build systems that make those moments simpler, more reliable and easier to use.
- I researchAI models can sound certain even when they are wrong. I study why that happens, how training changes their behaviour, and how we can make them more reliable.
- I writePayments and AI are moving quickly. I write to test ideas, challenge assumptions and work out what is genuinely useful.
