Welcome! I’m Justin Flick — a passionately curious technologist. My career has focused on data & systems engineering for AI/ML. After a stint as a Director of Engineering where I led an org of 30+ engineers for a Fortune 250 Insurance org, I’m now back behind the keyboard working on agentic AI solutions at Shopify.
This is where I write about the things I’m thinking about: data and ML engineering, software development, technical management, and the occasional hot take on how our industry does things.
