Solving Claude Code All at Once for Beginners - A Lecture by the Author of Claude Code Master
This is a tutorial-style Claude code development course that even beginners and those new to development can easily follow. Based on experience teaching offline classes for planners, designers, and non-developers, you can learn everything in a single flow—from basic examples not covered in books to intermediate development projects. Using Claude code, you will experience the step-by-step development process, starting from "Hello World" to a Lucky Draw app, a device-optimized cafe menu management web page integrated with Claude design and Excel data, and finally a SaaS web application that can be uploaded to databases and cloud services. Tutorials are provided in stages of theory, practice, and projects. Through six levels of hands-on exercises, you will master AI-collaborative development methodologies and experience the entire development cycle, including cloud deployment and operation.

Level 5 Lecture Hands-on Project Update and August Event Notice
Hello. This is Villain.
Following yesterday, half of the 8 practice sections for the Level 5 lecture have been uploaded as of today.
Due to an issue where Claude Code slowed down slightly last weekend, video production didn't go as smoothly as expected and took longer than planned; however, I will do my best to ensure that the Level 5 lectures are all completed this weekend.
In addition, for the August event, we plan to give away invitation tickets to a seminar taking place next month.
If you leave a course review, we will send invitations to the seminar on September 11th (Friday) to the first ten students on a first-come, first-served basis.
It starts at 7 PM at Hanbit Media Leaders Hall near Hongik University Station.
Please leave a course review and send your seminar application information (contact details, name) to my email (villainscode@gmail).
Please refer to the following image and text for the seminar topic.

1) Date and Time: Friday, September 11, 2026, 7:00 PM– (Entry available from 6:30 PM)
2) Lecture Content (Subject to change depending on the situation on the day.)
① Why 'Vibe Coding' hits a limit — The risks of coding by intuition
② What is a Coding Agent Harness? — The structure of context, tools, and guardrails
③ Harness Engineering in Practice: Turning Claude Code into a Controllable Workflow
④ Evaluator Design: Measuring Agent Responses with 'Metrics' Instead of 'Feelings'
⑤ Asking the right questions and evaluating properly — Designing prompts and Evals together
We will be sending free admission tickets (worth 20,000 KRW) to ten people who leave a course review, so we look forward to your participation.
Thank you.
