Hey, I'm John

I'm a Software Engineer currently building the future of commerce at Shopify. Previously, I've helped build PearAI, the open-source AI-powered code editor.

In my free time time, you can catch me on the tennis court, or fiddling with my Raspberry Pi.

About me

Hi! I’m a software engineer focused on building reliable, scalable systems, with experience across checkout and admin surfaces at Shopify. I have a background in aerospace engineering, which shaped my approach to writing precise, dependable software, and I now apply that mindset to complex production systems. I hold a Bachelor’s in Mechanical Engineering from McGill University and am currently pursuing a Master’s in Computer Science at Georgia Tech. I enjoy owning problems end-to-end; from design and implementation to testing, observability, and release.
