About the Author

Haggai Roitman has spent over two decades at the intersection of AI research and large-scale production systems. His work bridges theory and practice--from publishing foundational research to shipping systems that serve millions of users. His research interests span information retrieval, recommender systems, natural language processing, large language models, reinforcement learning for LLMs, and agentic AI. He has authored more than 100 peer-reviewed publications and holds approximately 100 patents. He earned his BSc (Cum Laude) and PhD from the Technion -- Israel Institute of Technology. When not thinking about gradient flows and KV caches, he can be found behind a set of turntables, mixing progressive trance and deep house.
