👋 Hello

I’m Hammad Fahim,

Based in Toronto, Canada.

I’m a machine learning scientist and NLP researcher with a PhD from the University of Ottawa, specializing in emotion analysis and model interpretability. I design datasets, train and evaluate transformer-based models, and ship them to production, working daily with PyTorch, Hugging Face, TRL, and the broader ML tooling stack. When I’m off the clock, I happily geek out about cars, bikes, and watches, and I’m usually planning my next trip.

Applied Scientist II

Amazon

May 2023 - Sep 2023

Built a GPT-based model in Python (Hugging Face Transformers) to predict appliance names from user utterances, engineered a distributed pipeline over 60M records, cut 8M faults in offline tests with significant accuracy gains, and presented the work at an internal Amazon conference.
