Yichuan Lin — AI Developer

About

Numbers person who happens to love interfaces.

I'm an actuarial & financial engineer finishing my master's at KU Leuven, currently developing probability-of-default credit-risk models with explainable AI at Reacfin in Belgium.

Alongside the quant work, I independently design and build websites — from requirements and responsive layout to UI/UX and client delivery. The two sides feed each other: modelling teaches me rigour, design teaches me how to make complex things clear.
