Hamidreza Shahidi

I’m a Senior Machine Learning Engineer at Instacart, working on generative recommendation to drive large-scale personalization and product discovery. My work bridges large language models and recommendation systems.

Previously, I was an Applied Scientist at Amazon, where I focused on optimizing retrieval and ranking in the ad serving funnel. Earlier, at Borealis AI (RBC), I worked on semantic parsing and causal inference.

I hold a Master’s in Computer Science from the University of Waterloo and a B.Sc. in Electrical and Computer Engineering from the University of Tehran.

There's more on my resume.
