[The 2nd edition is scheduled for completion in 2026] Presents various clean coding techniques.

Since the front-end is where the user comes into contact, it is very important to test from the user's perspective, not the developer's perspective. Through E2E testing, verify that the user scenarios work normally and experience the transition from fear to confidence in your code!

This course is for those who want to prepare for coding tests in the form of real mock exams. Each mock exam consists of 5 questions. It would be good to take my course, "Algorithm Problem Solving for IT Employment".

Master the complexities of React development, including custom hooks, TDD, the context API, refactoring, and complex state management.

In this course, you will learn NodeJS, which allows you to develop backends using the Javascript language, and develop API servers using NodeJS using the test-driven development (TDD) method. You will also understand the basic principles of ExpressJS, a representative web framework for NodeJS, and learn how to develop REST APIs used in mobile and web services.

This is a job-oriented QA practical course for beginners preparing for QA employment, where you will complete test cases and checklists used directly in the field by designing and performing tests yourself using real service examples.

With this course, you will be able to write clean and clear test code, exactly as it is developed in practice. This lecture is for anyone curious about why test code is necessary and what constitutes good test code.

What kinds of problems appear in coding tests these days? Solve “practical” problems yourself, reflecting the latest corporate coding test trends. We provide proven problems and solutions to effectively build your algorithm and problem-solving skills. (with Java)

A must-take testing course if you want to become a competent frontend developer. Master testing from beginner to advanced all in one go 👊

Software quality is a habit! This course will teach you how to become the best programmer that companies want.

Are you a non-major who doesn't know how to start learning C language? Did you learn C language as a major in school, but still can't write code? What's the point of studying C language for a long time? When you can't even create a single line of code properly... I'll pass on the know-how so you can program yourself. In this course, together with an experienced senior developer, you'll gradually learn C language grammar and application methods, and I'll guide you to a level where you can work on simple projects.

This lecture explains unit testing, UI testing, and integration testing methods in Flutter based on the official documentation.

Are you hesitant about writing test code? Experience the A to Z of Spring environment testing through this lecture!

Even if you create the same function, the code of a junior developer who has just learned JavaScript syntax and that of an experienced senior developer will be quite different. Of course, even if the results are the same. The reason the latter's code is recognized is because of its well-designed structure and scalability to respond to changes. This lecture will learn about how to create such good code.

By developing a simple ReactNative app using the TDD methodology, you will learn the concepts of TDD and practice applying them to ReactNative mobile app development.

This is an all-in-one curriculum for game programming beginners who are unsure of where to start. It is a comprehensive curriculum that covers the basics of game programming, including C++, data structures/algorithms, STL, game mathematics, Windows API, and an introduction to game servers.

When learning Swift, the iOS programming language, it can be confusing when multiple concepts appear all at once. That's why I created this course with the principle that "when understanding a new concept, only previously learned concepts should be used." So this course is meticulously designed with a sequential structure between concepts, where only one new concept appears at each stage, and no other unfamiliar concepts appear at all. One concept per minute, 180 concepts total. From the basics of variables and constants to understanding memory structure from a CS perspective, and even the latest syntax for asynchronous processing. In 3 hours, you'll learn 180 core concepts in the designed order.
