00 About
I like building things that touch real data and real people: an app for my school's dining hall, an AI voice agent that answers scam calls, and a look at whether ship traffic can say something about the oil market.
Before Dartmouth I deferred a year to work full time: business analysis at a traffic-tech startup in Tel Aviv, then research at Stanford's Memory Lab, UCSF, and scam.ai in Berkeley. I love learning something new and then putting it to work.
