I currently work on ML infra at Neuralink: foundation model training, Ray clusters, and Firecracker VMs for Grok agents.

Here on my blog I share my engineering notes and my love for the outdoors :) You’ll find me following fire roads until my phone loses signal, swimming in water that’s colder than it should be, and riding hundreds of miles to find a view no one has ever seen. I’m also racing with Triathlon Canada at the 2027 Multisport Age-Group World Championships.
