About Me
Wait, there's more?
Who is this person?
🎯 💻 ☕ 🔄
Hi! I'm Jiuhe (you can call me William if you prefer). I spend most of my time convincing AI models to do useful things while occasionally reminding them who's boss.
Some people talk to their plants; I read logs and call it "production system audits."
I've been shipping code for over 11 years now. Currently at a virtual bank in Hong Kong, making sure our AI agents don't accidentally give people more money than they asked for.
What do you actually do?
The Managerial Stuff
- Lead teams that build AI systems. The kind that mostly work but occasionally need a human to step in.
- Keep our data infrastructure from turning into a museum of legacy systems
- Talk to regulators so our AI doesn't break laws (boring but necessary)
- Coordinate between tech and business folks. Mostly translating "it's complicated" into "it'll be done Q2"
The Technical Stuff
- Build AI agents that work in production (not just demos that crash on edge cases)
- Wrangle LLMs, vector databases, and guardrails
- Design data pipelines that don't make our ops team cry
- Implement MLOps because "it works on my machine" isn't a deployment strategy

Random Facts
"He once fixed a production bug during his own birthday party.
The cake was had, the bug was fixed, the guests were confused but impressed."
-- Legend (slightly exaggerated)
- Master's in Quantitative Analysis, Bachelor's in Applied Physics (First Class Honors)
- Won some awards along the way. The real reward is when production stays up.
- Actually enjoy explaining complex technical concepts to non-technical stakeholders (rare, I know)
- Favorite debugging tool is still print statements. Don't judge me.
Fun Mode
When I'm not:
- Staring at logs trying to understand why production hates me
- Explaining to management why "just add AI to it" is more complicated than it sounds
- Updating Kubernetes configs because reasons
- Attending meetings that could have been emails
I apparently also:
- Exist (technically)
- Sleep occasionally (controversial)
- Drink coffee (essential)
