Zain Hasan

I build and teach AI.
Currently a Staff AI/ML Engineer - DX at Together AI, focused on large-scale models, tooling, and developer education.
I studied Engineering Science (ℕΨ) and did PhD work at the University of Toronto. Previously worked on vector databases at Weaviate, did data science in industry, and co-founded a health tech startup (Vinci Labs).
I teach on Coursera, DeepLearning.AI, and LinkedIn Learning, and have spoken at 40+ conferences on RAG, multimodal AI, fine-tuning, and coding agents.
