How I got here

For 15 years at Statistics Canada, I studied how technology shapes our society and economy, and grew the programs that continue this work. Then I took a One-Year AI Journey to build with it directly — shipping 40+ functional prototypes and founding Peji Systems to help organizations work smarter.

Curious experiments.

Based in Ottawa. When I'm not architecting data systems, I'm building 3D video games with my kids or writing on Substack.
