We enable you to fundamentally understand and resolve issues where Hangeul appears broken on web pages or in databases, or files contain unknown characters.

Automate repetitive Excel, Word, Outlook, and PowerPoint tasks using Python. You will implement projects based on real-world business scenarios and learn how to design and create your own office automation system, going beyond simply learning basic functions.

Refactoring is one of the basic skills that a software engineer should have. This course is designed to explain and practice various code smells and refactoring techniques in a more practical way using IntelliJ and Java.

Learn Java language grammar + basic programming skills + data structures at the same time.

I want to do data analysis and machine learning with Python programs. Isn't it difficult? First, you need to learn the basic grammar and basics of Python programs. This course will help you get out of the beginner stage.

This is a lecture for people who are starting development for the first time. It's about programming thinking, which should come before development languages or UI frameworks.

This course covers how to set up multi-module projects from scratch using Kotlin and Spring Boot. It proceeds with a hands-on approach, covering everything from the basic concepts of modularization to Gradle configuration, managing dependencies between modules, and actual application development. If you are a beginner or intermediate developer looking to learn the fundamentals and practical application of multi-modules, please refer to this course.

From the basics of Numpy and Pandas to data preprocessing, visualization, and crawling, all in one place! This is an introductory Python course for data analysis.

Even office workers who know nothing about coding can easily learn the basic concepts and grammar of programming through practice, and learn file input/output, Excel data processing, automatic creation of MS-Word documents, graph drawing, web scraping, etc.

It would be efficient to automate IT security tasks using Python, wouldn't it? This course follows hands-on practice, applying Python and web Flask development to automate tasks, idea by idea.

We present various clean coding techniques.

Knowing design patterns will make it easier to learn not only Spring but also many other technologies and programming languages. It will also help you develop more flexible and reusable object-oriented software.

Experience the Jeju-based bootcamp online! Quickly create your own service! :)

You can understand the theoretical operating principles of the Kalman filter through easy examples.

Develop a deep understanding and intuition for calculus. Solve problems and implement algorithms by hand and in Python.

This course is for those preparing for the CosPro Level 1 exam, covering the COS Pro Level 1 sample problems released by the exam organizer, YBM Net Co., Ltd.

When fixing legacy Java code, determine what to change and which behaviors to preserve. In the existing IntelliJ IDEA hands-on exercises, you directly review code changes, while in the 16 newly added theory lessons, you learn about names, functions, duplication, responsibilities, calling contracts, and validation criteria.

You will learn techniques that can be applied in various fields of IT security, starting from the introduction to Python programming.
