About

I work in Sales & Trading at a securities firm in South Korea — three years in, still learning something new most days.

Marginal Notes is where I write those things down: a market move that didn't make sense until I looked closer, a system that broke in an interesting way, an economics idea that finally clicked. Tech and finance overlap more than people admit — this is that overlap, in notes.

Personal views only — not my employer's, not investment advice.

Something wrong, or worth arguing about? I'd like to hear it.
