How I Got Here

Growing up, my parents told me: if you're not giving it everything, you don't love it enough. The things you truly love, you go all in on.

So whether I was slacking or grinding, they stayed out of it — with one line: you own the consequences.

Over time I got stubborn about it. Once I'm in, I'm in. As a kid I'd spend a whole afternoon on one math or physics olympiad problem — no food, no water, didn't move.

Later, almost by accident, I drifted from the world of math and physics into medicine and medication. The sheer density of knowledge, the discipline of the field — it felt new.

To me, medicine is a loop. From observing the body, to patterns in aggregate data, down into molecular mechanism, back up through how drugs act on the body, and back into the data. That's how humans have learned, all along.

In the AI era, I can turn an idea into a product almost without friction. Commercial or not, building is how I make an idea real.

I love this era. Just like my parents said — when you truly love something, you go all in.

What I Believe

"Most AI products optimize for sounding right. In medicine, sounding right is the failure mode — it's how a confident wrong answer becomes a denied claim, a missed diagnosis, a harmed patient. So I build the other way around: rules first, model second, every sentence in the output traceable to a source someone can audit. The boring version of safety is the only one that survives contact with a real patient."
