This book results from the author’s nearly two decades of industry experience in software engineering, data science, and Generative AI. Specifically, I could say nine years in software engineering, ten years in data science, and one year in building LLMpowered applications. However, by doing that, I would ignore the overlap among the three areas and not do justice to the role of emergent properties that a mind exhibits. The book suits laymen, technologists, business analysts, and business teams.
