The world of Generative AI can seem like a magic trick. One day, tools that write prose and code appear, and it’s natural to As a developer, where do I even begin? This book is your answer. It is born from a simple the most powerful way to understand this technology is not to theorize about it, but to build with it. Generative AI From Zero to Production is designed to be your practical companion on that journey. We will move systematically from your first API call to the complexities of deploying a resilient, full-stack AI application. You will not just learn concepts; you will build a portfolio of projects that demonstrate a critical transition—from being a user of AI interfaces to a builder of AI-powered systems. The path ahead is projectshaped. We will construct intelligent chatbots, create knowledge-aware assistants, automate workflows with agents, and finally, tackle the crucial engineering challenges of taking these prototypes into a production environment. The code you write, the patterns you learn, and the architectural decisions we discuss are all drawn from realworld scenarios. Our tone is that of a guide. We will be direct about what works, warn you of common pitfalls, and celebrate the "aha!" moments that come from seeing your code spring to life with intelligence. The field of AI will continue to evolve, but the foundational engineering skills you learn here—how to reason about, construct, and deploy these systems—will remain invaluable. Let's start building. — Ram Padda
