I live in a small town in the middle of South Korea.
This is the story of my career change after I decided to quit my IT job and pursue something more physical.
For seven years, I worked as an IT developer. I built communication systems during the day and tinkered with personal projects at night. I loved connecting a Raspberry Pi to Telegram to create remote control systems. That feeling of building something real kept me going. However, something started to shift.
The Turning Point: When I Began to Question Tech
The turning point came when I started using commercial IoT products from global tech giants. I noticed a clear difference. Their products were stable and polished, while mine were functional but limited by my resources.
This gap made me ask uncomfortable questions about my career path. I wondered:
- Could I realistically compete with well-funded teams?
- Was there a ceiling to my growth without joining a major corporation?
- As AI and automation accelerate, would my technical knowledge still be a differentiator in ten years?
I realized that software would eventually perform repeatable patterns better than people. I didn’t want my future to be something an algorithm could easily replace.
Searching for Irreplaceable Human Skill
I spent months thinking about the kind of work I wanted to do long-term. I wanted work that required a kind of precision and judgment that an algorithm couldn’t replicate.
I kept coming back to one idea: Physical Craft. I wanted to work in the real world with real materials. I wanted a career where ten years of experience makes you meaningfully better, not just more efficient at a repetitive task.
Why Professional Car Detailing?
I know how it sounds. A developer quits tech to polish cars. It’s a career change that raises eyebrows. However, professional car detailing requires an obsessive attention to detail—the same trait that made me a good developer.
In detailing, the margin for error is tiny. One moment of inattention can damage a paint surface. The feedback is immediate, physical, and permanent. Unlike code, a perfectly detailed car doesn’t crash, doesn’t need a patch, and doesn’t get deprecated. It simply remains a masterpiece of human skill.
7 Years Later: Where I Am Now
That was the bet I made seven years ago. Today, I am still here—still learning, still improving. I am currently setting up my own workspace, building something that is fully mine.
The path from developer to detailer wasn’t straightforward, but I haven’t second-guessed it once. I believe that real skill applied to real objects by human hands is harder to automate than most people expect.
I’ll be writing about my journey here—the craft, the business, and the reality of professional detailing. If you’re curious about making a major shift yourself, I hope my story provides some value.
