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

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"

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

C++ programming methods required in the field! It's time to move beyond C-style coding and start coding like a true C++ developer. This course is designed to help you build fundamental programming skills by learning the basic syntax of C++ step-by-step, growing to a level where you can apply them immediately in real-world practice. You can create practical projects using Arduino or develop the programming skills necessary for game development using Unreal Engine. Through this course, you will naturally boost your programming confidence and become comfortable utilizing C++ in practical applications.

This is a course where you can learn UML and object-oriented design even without programming experience. Concepts are explained through everyday examples (cafes, libraries, shopping malls), and you'll learn 9 types of UML diagrams step by step. You'll develop design skills that can be immediately applied in practice using theory and PlantUML.

If you use JS but find it difficult to explain why it works, this course provides the answer. From execution context, closures, and the event loop to Promise concurrency, prototypes, Virtual DOM, memory leaks, and bundle optimization—you won't just read about 18 chapters of advanced JS concepts; you'll learn by seeing them happen right before your eyes with a simulator. Code-based quizzes are provided for every chapter, and you can own it for life for the price of a single chicken dinner.
