From theory to software.
Building carefully, learning constantly.
I’m a Quant Developer at Millennium and a Project Lab Mentor for the University of Chicago’s Financial Mathematics program.
I studied Computer Science at the University of Chicago and Mathematics at UT Austin. Outside work, I make educational videos, speedcube, collect playing cards for cardistry, and play table tennis competitively.
