It's the most practical guide for those seeking a new future for developers in the AI ​​era.

A realistic story of AI development for developers in the chaotic AI era.

Bae Hwi-dong, "Developer Who Codes Vibes"
We view programming not as simply implementing functionality, but as a creative act driven by rhythm and sensibility. We collaborate with AI coding agents and experiment with new workflows, including automated testing and the use of external memory.
His writing suggests ways to make development more enjoyable and smarter, even if you're not an "AI developer."

Hong Seok-yong: "I am an AI platform developer."
He shares his experience starting out as a cloud infrastructure engineer and fundamentally changing the way the organization works by building an AI platform (KAP) at Kakao.
It vividly shows the process by which platform developers solve organizational problems through systems.

Oh Hyun-woo's "Becoming a Global AI Solutions Engineer"
Starting with Kaggle experience, we will present examples of applying AI solutions to corporate problems in global settings.
It highlights the importance of cultural differences and communication skills, as well as technical skills, and presents a new perspective on addressing AI on the international stage.

_Jeong Geum-ho, "Living as a Developer in the AI ​​Age"
Working as a full-stack developer in Germany, he shares practical examples of using AI as both a tool and a collaborator, including automating API summarization, collaborative workflows, and building GPU pipelines. He offers practical AI utilization strategies even for developers who aren't AI specialists.

Namgyu Choi, "An AI Backend Developer's Career Transition and Growth Record"
He tells the story of how he grew from a backend developer to connecting and operating AI systems.
Through a perspective that prioritizes architecture and operational stability over models, it persuasively demonstrates why backend development remains important even in the AI ​​era.

Kim Seong-wan, "AI Development Insights from AI Researchers"
From fuzzy theory to generative AI, I document the AI ​​innovations I have witnessed firsthand as a researcher.
This book presents the essence and direction of AI technology through a perspective that bridges academic depth and practical application. Beyond learning AI as a "tool," it teaches students how to "understand" it.

“Technology is always moving fast.
But ultimately, it's up to each person to understand, utilize, and incorporate that technology into their career and life.
I hope this book will serve as a small compass for all readers seeking their way in the AI ​​era.”
