C++ Principles Known Only to the 1%: How to Create a Gap at the Introductory Level

This is a practical Qt QML and C++ course strengthened by 6 essential, hands-on projects. Build your professional foundation through exercises covering everything from various types of UI development to REST API communication!

GPGPU is no longer an unfamiliar technology. It has long been utilized in various fields such as scientific computation, simulation, and graphics processing, and today, it has established itself as the core foundation that determines the performance of AI technology. In this context, GPU programming skills serve as a powerful tool that expands a developer's capabilities to the next level. Moving beyond CPU-centric development to directly handling large-scale parallel computing means acquiring a new way of problem-solving and broader development possibilities. This course systematically covers CUDA programming—the de facto standard of GPGPU—from the basics to practical application. The curriculum focuses on content that can be immediately applied in practice, including understanding GPU architecture, parallel programming models, memory optimization, and kernel writing. The goal is to reach a level where you can design and implement GPU-based programs on your own after completing the course.

You can get started with desktop app development using Qt QML and C++. This course focuses on development targeting the Windows operating system. Development is also possible on macOS using the same methods.

This course is for those who are preparing for an algorithm test using the C/C++ programming language. The purpose of this course is to develop problem-solving skills using algorithms and data structures.

Take the leap from a beginner to an intermediate developer by learning Qt/QML programming skills and the latest technologies through real-world projects.

Don't practice C in a boring environment, have fun practicing C by building real, usable Windows applications.

The best coding test lecture that helped students pass Naver, Kakao, and Samsung coding tests in just 10 weeks!

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".

Are you having trouble using CMake? After taking this course, you too will be a CMake expert.

Learn the basic C++ syntax for smooth learning of the series. We will cover essential content from assembly language to basic C++ syntax, STL, and C++11 in a compressed manner.

Scala allows you to write much more concise and robust code quickly, while still leveraging the experience you have gained as a Java developer. This course is designed for Java developers to quickly understand the overall look of Scala based on their existing Java knowledge. If you are an existing Java developer, you can learn Scala very easily.

Through the 25 patterns of OODP, you will learn various ways to design software in an object-oriented manner.

This is an introductory Java course designed so that even those starting programming for the first time can follow along. You will systematically learn everything from JDK 21 environment configuration to variables, data types, control flow statements, arrays, strings, and the core concepts of Object-Oriented Programming (OOP) such as classes, inheritance, polymorphism, and exception handling. Rather than simply listing syntax, we explain "why it works this way" to help you build a solid foundation.

This is the process of refactoring a game engine made with C++ using the DirectX 11 library. It was developed by inferring internal code, allowing you to think about the internal principles of the Unity engine. This is not a project at the level of a rendering program typically covered in academies/lectures. It builds a real game engine incorporating various technologies, from the build system and scripting.

Through training in thinking, expressing, and coding, you can easily understand and approach Java programming. You can understand the relationship between programming elements and gain confidence in future Java API utilization and projects through precise concept organization of object-oriented programming.

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.

This course goes beyond simple grammar explanations and focuses on developing C++ programming skills that can be applied immediately in the field. Throughout my teaching, I have directly addressed common challenges faced by many learners—such as struggling to understand the STL or feeling confused by file handling and exception handling concepts. Based on this experience, I provide step-by-step explanations to ensure even complex concepts are understood easily and clearly. Furthermore, this course is not just about delivering theory; it is structured around: 👉 "Why this concept is necessary" 👉 "How it is used in actual code" 👉 "How it is applied in professional practice"

Learn various design principles needed to write object-oriented code, focusing on working code.

You can systematically learn stock trading automation using Python and the Interactive Brokers API, which holds the top spot in global market share.

This is the process of creating a game engine using C++, similar to the Unity game engine. It was created by inferring the internal code, and through this, we can think about the internal principles of the Unity engine.
