I’m engineering Privacy and ML features at Firefox for 250M+ users and built open-source tools (MarkUs & PythonTA) used by 10k+ students. Also leading Blueprint, UofT AI. This summer I’m doing quantitative research on a front-office trading desk. Previously won (Hack the North, UofTHacks, Google’s Toronto Hackathon) and organized Anthropic’s Toronto hackathon.

I read a lot of history & geopoltiics in my spare time (see reading list). In high school I placed 1st in Ontario and 5th Nationally in debate, coaching many cohorts of students. Previously a competitive swimmer, I’m now a triathlete training for the national age group team, racing a few Ironmans and ultra events this year.
