A home page is a strange thing to write. Here’s what I’d tell you if we met!

Interests and recent work

  • Engineering at Shopify on the Sidekick+ CX R&D team.
  • Seven months at Mozilla doing applied ML and networking research on Firefox’s privacy team. Built models to defend hundreds of millions of users from the trackers and fingerprinting scripts that quietly run on almost every page of the open web.
  • Built Firefox’s new tab widget surfacing metrics for enhanced tracking protection. Closed a handful of security bugs along the way.

Ultra running and triathlons

I race ultras and triathlons! Training for the Canadian team for 2027 worlds.

Silly facts

  • I’ve always loved geography. I have a small collection of maps I find interesting, and play a lot of GeoGuessr!
  • All my belongings live in one 40L black duffel. I care a lot about the environment and am strongly against fast fashion.
  • I think analog synthesizers are some of the most beautifully engineered objects on earth.

Questions I’ve been thinking about

  • How can I get better at setting medium-term goals?
  • What would 30-year-old me wish 20-year-old me had spent more time on?
  • How can I be a better brother?
  • How do I stop getting injured? :)
