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.

Complete the core battle system of a Unity 2D martial arts idle game from scratch using the AI coding agent Claude Code. We will build a starter kit codebase that is immediately expandable in practice—covering auto-battle, object pooling, stage systems, and boss battles—while experiencing the entire development loop from requirement design to debugging alongside AI.

Completing an integration project between an API server built with Spring Boot (ver 3.4.x) and React 19 (with TypeScript)! Applying front-end to a back-end portfolio! A course written for working professionals (not a beginner-level course).

We have entered an era where it has become incredibly easy for web developers (especially React developers) to launch apps. With Expo, you can release both Android and iOS apps even faster. Let's become developers who can quickly launch apps through Expo.

In this course, you will learn about TypeScript.

We will develop an avatar-based community app using React Native. You will learn the process of creating a high-quality community app that includes not only post creation but also comments/replies, likes, polls, and avatar generation.

This is a practical course for those who have completed the introductory Godot Engine course. We will implement the core logic of a Breakout 2D game together.

In this course, you will be able to create a Reddit website from scratch, step by step.

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.

Learn Springboot + NextJS RestAPI Board Creation Faster Than Anyone! Develop a CRUD server with Springboot and create your own board with NextJS!

"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.

How are you using TypeScript, the standard of Node.js? If you only add type annotations, it is not real TypeScript. I prepared everything because I don't know what you will like. Let's learn TypeScript A to Z :)

This article explains in detail how to create a 'Matching Pictures' card game using Godo Engine.

If you don’t know why things keep breaking when you have AI do it, the problem isn’t coding—it’s telling it what to do without understanding “what’s happening.” I’ll teach you vibe coding by taking a web service with login and payments from scratch all the way to launching it on your own domain and getting it indexed by search engines, while understanding the context behind “What just happened?” at every step.

You will learn about what a node is, the latest JavaScript grammar, the node API, npm, the module system, databases, testing, and more. You will create a project using five practical examples. You will also deploy a service to the cloud and convert a node project to TypeScript.

A course to learn the latest Node.js backend REST API using fastify, a Node.js framework boasting high speed, ORM Prisma, and Typescript.

I recommend this to those who want to learn how to easily create and distribute Android apps, Windows apps, and iOS apps. We will teach you the basics of TypeScript rather than JavaScript and Angular!
