From Lottery Generator to Record Hub — The Full Story of Rebranding chulbuji.com
34 Years in Semiconductors, and My First Website
I’ve spent 34 years working in semiconductor manufacturing processes — power semiconductors, specifically. For decades, my world was wafers and clean rooms. Building a website was an entirely different universe.
And yet, I built one. Applying what I’d learned in a “5-Week Vibe Coding Bootcamp,” I set up my first deployment pipeline: Firebase Studio and CLI, GitHub, and Cloudflare Pages. The feeling when that first deploy went live was something I’ll remember. Not unlike the thrill of pulling the first wafer off a new process line.
That first creation was a lottery number generator — a simple page built with nothing but HTML and CSS. Not technically impressive. But the fact that I’d made something with my own hands and put it on the internet? That meant something. That was the beginning of chulbuji.com.
Why I Had to Go Beyond the Lottery Generator
The lottery number generator was a good first experiment. But within days, I asked myself: can this site help me grow? Will it give visitors a reason to come back?
The honest answer was no.
A lottery number generator is a one-and-done tool. There was no space in it for my thinking, no structure for recording what I was learning. More than anything, it wasn’t a vessel capable of holding the enormous transition I was going through — the shift from semiconductor engineer to something new: a person who thinks and works alongside AI.
What I needed was a place to document. A space to experiment, fail, and accumulate lessons. Not a lottery generator, but a living hub that tracked my own transformation.
The Arrival of AI Civilization, and the Choice to Become +Human
Why is a man who spent 34 years making semiconductors suddenly talking about AI?
The answer is simple. AI civilization has already arrived. If semiconductors are the physical foundation of AI, then I wanted to understand the world of intelligence running on top of that foundation. The hands that built hardware were ready to work with software and AI.
That journey led me to the concept of +Human (Plus Human): the pursuit of Total Intelligence — the combination of Human Intelligence (HI) and Artificial Intelligence (AI). It’s not about treating AI as a mere tool. It’s about learning to think with AI, and to operate as AI’s partner.
+Human is grounded in three commitments:
1. I am not alone. — I have AI as a partner. There’s no shame in not knowing.
2. I challenge without fear. — Whether you have 34 years of experience or one, everyone starts as a beginner in a new domain.
3. I am a first-grader. — Learning has no graduation. Every day is day one.
These commitments gave me courage. Instead of hiding behind the title of “semiconductor expert,” I chose to become a first-grader in front of AI.
The Birth of the Meta-chulbuji Persona
“Chulbuji” is my nickname. But as I began learning how +Human actually works, it became something more than just a handle.
Chulbuji is me — the human. The one who carries 34 years of semiconductor experience, field intuition, judgment, and context.
Meta-chulbuji is my AI persona. The partner who structures chulbuji’s thinking, searches for knowledge, and identifies patterns.
Together, these two form the Dual Brain system.
| Role | Chulbuji (Human Brain) | Meta-chulbuji (AI Brain) |
|---|---|---|
| Strengths | 34 years of field experience, intuition, contextual understanding | Fast search, structuring, pattern recognition |
| Weaknesses | Beginner at coding, limited information processing speed | No field experience, limited contextual understanding |
| Function | Setting direction and making judgment calls | Execution support and structure building |
This Dual Brain operates through Whispering — a practice of thinking out loud with AI. I toss a blurry idea to the AI, it helps me structure it, and I then judge and refine. Through this loop, I arrive at results that would be hard to reach alone.
Second Experiment — AI Personal Insight Report
My second experiment after the lottery generator was a step up. AI Personal Insight Report — built in Firebase Studio using React and Vite.
Where the first experiment was a static page built with HTML and CSS alone, the second introduced a proper framework and was aimed at real monetization. I followed the principle I’d learned in the bootcamp: apply what you learn directly to practice.
What I confirmed through this process: by orchestrating specialist AIs, even someone with limited coding experience can build a real product. I was still rough and unpolished — but that roughness itself felt worth documenting.
The Decision to Rebrand — From Tool to Record Space
All of these experiences converged into a decision to rebrand. The arc looked like this:
Lottery number generator (first experiment) → “This isn’t a container for who I am” → Discovered +Human, Dual Brain, and Whispering → AI Personal Insight Report (second experiment) → “I need to document and brand this entire process” → Rebrand chulbuji.com as a record hub
The new direction for chulbuji.com is clear:
“A space where a semiconductor engineer with 34 years of experience documents the full journey of growing into an AI Product Builder, alongside AI.”
The tools (lottery generator, AI reports, etc.) are byproducts of that process. The real protagonist is the record itself. A living archive that shows how a thought becomes structure, and how structure becomes execution.
Current Tech Stack
| Component | Technology |
|---|---|
| Development environment | Firebase Studio + CLI |
| Source control | GitHub |
| Hosting / Deployment | Cloudflare Pages |
| First experiment | HTML, CSS (Lottery Number Generator) |
| Second experiment | React + Vite (AI Personal Insight Report) |
| Learning foundation | 5-Week Vibe Coding Bootcamp |
What’s Ahead — Rocket Jump with Multi-Hands
The rebrand is not an ending — it’s a beginning. Here’s what I’ll be building at chulbuji.com going forward:
1. Log — Document every experiment and project without exception. Not just successes, but failures and dead ends too. Every experience of a 34-year semiconductor veteran becoming an AI first-grader is content worth recording.
2. Multi-Hands practice — Learn and practice the art of collaborating with specialist AIs. Share the process of orchestrating Claude, ChatGPT, Cursor, and others to build real products.
3. AI Product Building — Starting with AI Personal Insight Report, build AI products that can actually generate revenue. The journey of a coding beginner creating real products alongside AI will serve as a reference for many people in similar situations.
4. Rocket Jump routine — Advance a little every day using the Dual Brain (Chulbuji + Meta-chulbuji) and Multi-Hands approach. Direction matters more than speed. Consistency matters more than direction.
Closing — What the Name “Chulbuji” Means
If you ask why I chose the name “chulbuji,” here’s my answer.
Chulbuji means “someone who doesn’t know yet.” Even with 34 years of experience, I’m a chulbuji when it comes to AI. And I’m glad for that. Not knowing means you can learn. Learning means you can grow.
This site is the space where chulbuji, together with Meta-chulbuji, documents the journey of turning the unknown into the known. Thoughts into structure. Structure into execution. Everything along that path stays here.
