Meet the Author

Hi, I'm Vajo Lukic! I've been exploring the worlds of data engineering and solution architecture for over 20 years, dabbling in everything from machine learning to business intelligence. I love getting my hands dirty with code and data, and crafting smart systems. I'm always on a quest to learn something new and share that knowledge with anyone willing to listen.

Reading Isaac Asimov's "Robot" series as a teenager really sparked my imagination about AI and what machines could become. Years later, when I first used ChatGPT and saw it behave exactly like the AI assistant from the films I loved, I was blown away again. That experience — combined with my professional work in data and machine learning — inspired me to write this book.

When I started learning about ChatGPT, prompts, and large language models, there were so many concepts I wasn't familiar with. As time went on, I studied these topics and began to understand them one by one. While learning I made notes and collected helpful resources. After a while, I realized I could put all this information together and share it with others as a useful study tool. That's this book.
