"Why did the AI write this code?" or "Why can't it remember what I just said?" The frustration you encounter when using AI tools like Claude Code stems from not knowing how the tool actually works. This course flings open that black box. Over 25 lessons, we will build our own Coding Agent from scratch that functions exactly like real-world professional tools—giving the LLM 'eyes' to see files (Read), 'hands' to fix code (Edit), and 'feet' to execute commands (Bash). This isn't just about learning how to use a library. You will gain hands-on experience by implementing code to understand how AI perceives project structures, why it loses its memory during long conversations, and how to solve those issues technically (Sliding Window, Summary). Through this process, you will evolve from being a mere 'user' of AI tools to an 'AI provider' who understands the underlying principles and can customize and evaluate tools to fit your specific needs.

Many people write. But most of those writings end up buried in files. This lecture starts from that point. ✔ “Why does nothing happen even when I write?” ✔ “How can I connect my writing to opportunities and money?” Through 26 years of corporate experience and actual writing, publishing, and lecturing experience, I have personally built a structure where writing becomes an "asset." In this lecture, I will share more than just simple writing techniques; I will show you specifically how to: 👉 Take a finished piece of writing → Expand it into blog posts/content → Build it into a portfolio → Connect it to lecturing, publishing, and business opportunities In particular, I will explain the entire flow based on realistic standards: How a single piece of writing expands into content How 5 pieces of writing become a lecture How 40 pieces of writing become a book By the end of this lecture, your writing will no longer be just a "record," but an asset that works on your behalf.

Supabase, the wings for your full-stack development! Through three clone projects, you will quickly learn how to perform professional-level full-stack development using Next.js 14 and Supabase.

We solve the fundamental problem of losing control amidst AI-generated fragmented code and the complex React ecosystem by opening the hood and engineeringly analyzing the internal workings of core React libraries such as Zustand, TanStack Query, React Hook Form, Zod, and the React Compiler. By moving beyond simple tool usage and mastering how to directly manipulate the performance and data flow of the React engine, you will build the solid 'enterprise architecture design muscle' necessary to respond immediately to any crisis.

The Next.js 15 App Router is a powerful architecture for building high-performance web services by perfectly controlling the boundary between server and client. This course clearly connects complex rendering mechanisms—from the operating principles of React Server Components (RSC) to the three major caching strategies (Static, Dynamic, and ISR)—through 12 practical missions. Through this, you will gain the ability to design file-system routing and nested layouts according to business requirements, completely breaking free from the anxiety of "vibe coding" where you copy code without understanding the principles. Ultimately, you will evolve into a Next.js architect who can instantly spot the blind spots in AI-generated code and proactively direct the optimal structure.

This course is a practical, hands-on guide for those who want to learn how to maximize development productivity in the AI era. Beyond simply learning how to use AI, we focus on how to utilize Claude Code in a real-world development environment and how to produce "proper results." Many developers use AI but still face issues such as: ❌ Inconsistent results ❌ Poor code quality ❌ Increasing project complexity To solve these problems, this course teaches you how to utilize AI as a "development partner" rather than just a tool through: ✔ Spec-based workflows ✔ Structured command systems ✔ Sub-agent and automation strategies Furthermore, you will gain the experience of completing and deploying a full application from start to finish by integrating with real-world services such as Firebase, Figma, GitHub, and Vercel.
