Introduction to the MAKER

Hello, I am Saintoo, a 20-year veteran IT developer.
'Saintoo' means 'an investor who understands the world and humanity.'
I aspire to be a creator who understands people and the market, not just a developer who knows technology.
Experience accumulated over 20 years in the IT field
From developing systems for large corporations to running my own business, I have personally experienced how technology connects to real business.
In particular, I developed the ability to simplify complex systems and design them so users can easily utilize them.
This experience is now greatly helping me explain how ordinary people can easily use AI.
In 2008, turning 3 million won into 600 million in annual sales
I founded the online shopping mall 'I Love Moon' and successfully operated it for seven years with four employees..
I achieved various accomplishments, including interviews with Living Sense magazine, publishing a book, and having products featured in variety shows and dramas.
However, at that time, all blog marketing and product page writing were done manually.
I always thought, 'How great would it have been if AI had existed back then?'
In 2025, a fateful encounter with AI
Just four months after I started my Naver blog in earnest, I achieved optimal grades 3 to 4, daily visitors increased tenfold, and I surpassed 1,000 neighbors. The secret was utilizing AI.
I started programming in sixth grade, majored in computer engineering in both high school and university, and even received a full scholarship by self-studying for the college entrance exam... but technology alone was not enough.
Through running the shopping mall, I realized that 'true value is created when technology, business, and storytelling come together.'
Through real estate investment, I built assets worth 3.5 billion won in two years, hosted over 30 book clubs, and gave more than 10 lectures, learning the joy of sharing knowledge.
This book is the culmination of my 20 years of know-how. It is not just a collection of my experiences,
I have completed the best content by researching AI-related lectures and professional materials from around the world, sparing no expense or time.
However, it felt too valuable to keep to myself. I wanted to share the changes I achieved with AI with more people.
In particular, I wanted to help those who, like me, are not familiar with technology to easily follow along.
That's why I chose Wadiz. It's not just about selling a book, but about growing and communicating together with supporters on this platform.
Through your vivid feedback, I want to continuously develop more practical and effective ways to utilize AI.



















Reason for choosing Wadiz
I want to share the AI know-how I have accumulated over 20 years in the IT field with more people.Beyond simply selling an e-book, I wanted to directly communicate and understand which parts are difficult and what kind of help is needed as supporters actually generate income with AI.
I believe Wadiz is a platform where makers and supporters can grow together. Through the vivid feedback from supporters, I will continuously develop more practical and effective AI monetization content.
Future funding usage plan
The funds will be invested in AI technology research and improving content quality.
They will be used for researching the latest AI tools and platforms, subscribing to overseas AI professional materials, and conducting practical tests to provide more useful guides to supporters.
In addition, I plan to continuously invest in technology development and resource acquisition needed to enhance the quality of future AI-related e-books and lecture content.
To ensure supporters always have access to the latest and most effective AI monetization methods, I will spare no effort in continuous learning and research.
