Before his work on Copilot, John built an impressive career as a search engineer. His diverse experience includes helping to develop next-generation search system for the US Patent Office, building search and recommendations for Eventbrite, and contributing to GitHub’s code search infrastructure. John is also coauthor of Relevant Search (Manning), a book that distills his expertise in the field.

John’s unique background, spanning both cutting-edge AI applications and foundational search technologies, positions him at the forefront of innovation in LLM applications and information retrieval.

Albert Ziegler has been designing AI-driven systems long before LLM applications became mainstream. As founding engineer for GitHub Copilot, he designed its prompt engineering system and helped inspire a wave of AI-powered tools and “Copilot” applications, shaping the future of developer assistance and LLM applications.

Today, Albert continues to push the boundaries of AI technology as Head of AI at XBOW, an AI cybersecurity company. There, he leads efforts blending large language models with cutting-edge security applications to secure the digital world of tomorrow.
