I can finally say this out loud. I have released my first book, Design System Step by Step.

This is a concise and practical guide for teams that want to move faster, reduce product chaos, and build products that scale without their UI falling apart. It shows how to build a design system as a real product: from visual foundations and tokens to components, documentation, and long-term team scaling. No unnecessary theory. Only what actually brings structure, clarity, and predictability to interfaces and development.

This book is written for professionals working with real products and complex systems. Not as a tool tutorial, but as a system framework.

But more importantly, this book is the quintessence of my 20-year career in design. I’ve worked across many disciplines, explored different directions, and learned from each of them. Over time, one thing became clear: attention to detail, care, logic, and consistency are what allow products and teams to truly scale. Design systems became the natural outcome of this mindset. A way to turn all of that experience into a practical framework that helps real teams build better products.
