Learn vibe coding, one level at a time.
The intro course is free. Beginner through Advanced run as solo practice, and Team Lab continues as a team project.
Course structure
Six levels, Intro through Enterprise
Intro through Advanced are solo practice. Team Lab is a team project, and Enterprise works on an existing system.

What each level covers
What you build in one level carries into the next.
- LEVEL 1Solo practice
Intro
Free
Describe a program to AI in plain words, run what comes back, look at the result, and change the parts you do not like.
What you do
- Describing what you want so AI can act on it
- Running the code you get on your own machine
- Asking again when the result is off
The goal here is the first "oh, it works" moment. Shaping it into a service comes later.
- LEVEL 2Solo practice
Beginner
KRW 30,000
Own one feature end to end. Writing down what you need, putting a screen on it, and tracking down what broke starts to feel routine.
What you do
- Turning an idea into something you can hand over
- Laying out a UI
- Adding a feature and changing it
- Reading an error and finding the cause
This is one feature at a time. Wiring several together into a service comes a little later.
- LEVEL 3Solo practice
Intermediate
KRW 50,000
What happens behind the screen comes into view. Once you can see where data lives and how it moves, the range of what you can build widens fast.
What you do
- Thinking about frontend and backend separately
- Moving data over an API
- Storing and reading from a database
- Handling login and permissions
- Undoing work with Git
- Connecting a third-party service and trying realtime
Still on your own for now. Splitting the work across people happens in Team Lab.
- LEVEL 4Solo practice
Advanced
KRW 100,000
Reading and changing code you did not write stops being daunting. You add to an existing program, tidy it up, and deploy it.
What you do
- Finding your way around unfamiliar code
- Pinpointing where a change belongs
- Fixing bugs and tidying code
- Writing tests and running them
- Working in separate branches
- Deploying it for real
By here you can handle most things solo. Next you do it alongside other people.
How it works
Learning and practice come as a set
You submit each assignment, apply the feedback, and move on to the next level.
- 01
Learn
See what you are building this time.
- 02
Build
The instructions sit beside your workspace, so you build as you read.
- 03
Submit
Hand in what you made.
- 04
Feedback
Find out what to change and why.
- 05
Next
Fix it, then move on.
Team Lab
Planned, built and deployed as a team
KRW 300,000
Team Lab
A team of five to ten builds one service together, from planning through deployment. The development environment, servers and sample data are set up to fit the project.
What teams build
Online store
List products, put them in a cart, and carry that through to orders and payment.
- Environment
- Server
- Sample product data
Messenger
Move messages in real time, then add read receipts and who is online.
- Environment
- Server
- Sample account data
HR system
Handle organizations and members, and make attendance and approvals flow.
- Environment
- Server
- Sample org data
Game
Set the rules and scoring, and keep it from falling apart when everyone joins at once.
- Environment
- Server
- Game assets
Marketing tool
Manage a contact list, send messages, and gather what came back.
- Environment
- Server
- Sample contact data
POS / Kiosk
Build what actually happens in a shop: taking the order, the payment, and the ticket that lands in the kitchen.
- Environment
- Server
- Menu and store assets
Roles
- Frontend
- Backend
- Database
- AI
- QA
- PM
Roles are split per project without confining anyone to one area. You read and change code in other parts as the work requires.
How the team works
- Git
- Branch
- Issue
- Pull Request
- Code Review
- API Specification
- Database Schema
- Conflict resolution
- Test
- Deploy

getTotal is missing qty. Multiply by it inside the reduce.
Enterprise
Analyse and change an existing system
KRW 1,000,000
Enterprise
A project course working on a codebase at production scale.
You work out how an unfamiliar codebase fits together, scope the impact of a requirement, then make the change and take it through testing, code review and deployment.
Systems you may be handed
- An existing HR system
- An existing CRM
- An existing ERP
- An existing internal system
- A large web application
How it runs
- 01Read the code
- 02Map the system
- 03Analyse the requirement
- 04Trace the impact

For teams
Running this with a team
Get in touch if you are bringing this in as internal training or running it with a whole team. Team Lab and Enterprise were built for teams from the start.
Frequently asked questions
Is this workable if I have never written code?
The intro course assumes you have not. Follow the screens from installation through to running it and you will be fine.
Can I just take the free intro?
Yes. You can take the intro course without paying and decide afterwards whether to continue.
How much time does this take per day?
There are no fixed class hours. You work assignment by assignment, so you go at whatever pace your week allows. Intro through Advanced back to back runs about three months.
What happens when I get stuck on my own?
Submit the assignment and you get feedback on what to change and why. You are not left to carry a blocker into the next assignment.
How are Team Lab teams put together?
Five to ten people per team, with roles split across Frontend, Backend, Database, AI, QA and PM to fit the project. You also build outside your own role using AI.
Who is Enterprise for?
People who want practice reading and changing code that already exists. Where Team Lab builds something new, Enterprise hands you a running system to modify and deploy.
Can a whole team at my company take this together?
Yes. Team Lab and Enterprise were designed for teams. Get in touch through the team training enquiry.
