I Built an AI Agent on 75 Years of F1 Data — Here is How It Works

A first-person walkthrough of building a natural language data agent from scratch: the architecture, the tools, the blocker that changed everything, and what I learned about how agents actually work in practice. I am a data engineer, not an AI researcher. I have never trained a model. I do not have a machine learning background. But I wanted to understand AI agents properly - not from a tutorial, but by actually building one end to end.
