Cultivating Programming Thinking for Development

And we are in the era of AI now. In the past, the "app-first" approach was difficult. Someone had to give you the code—whether you copied it from a book or found it on the internet. But now, we have AI. If you say, "Make me an app," it actually generates the app code. This is a complete game changer. Now, anyone can have an app from day one. And while looking at that app, they can ask, "What is this?" The method I used 10 years ago is now something anyone can do.

This is a course where you can learn about the app development process and what elements you need to study. It covers very basic parts, from screen composition to data management and screen transitions.

Don't study hard from start to finish to build an app! SwiftUI, take out a piece at a time when you need it!

Are you learning grammar in the terminal? Are you studying grammar while typing? Please stop studying stiff grammar! Let's quickly learn Swift's grammar, which is essential for developing mobile apps!

This is not a class where you just follow along, but an app that builds the foundation. It's a time to learn what it takes to create the things we want to create.

Have you ever wondered why you can't understand developers' conversations even though your development knowledge is increasing? Even if you don't have specific development knowledge, there are many cases where you need to know the terms developers use to understand the exact meaning. Quickly learn developer terms!

Before you start developing, you can learn how to use the collaboration tools that you must use when developing. Rather than listening from beginning to end, it would be better to pick out the concepts you don't know or the parts you need.

This course is an introductory course for the general public who want to create a simple app. It builds basic knowledge of iOS development. In Part 2, you will learn the core Swift grammar and concepts, create a simple app, and build the basics of development.

To become a good developer, you need to know how to write flexible code. Learn how to use object orientation to create flexible code that is easy to change.

This is a course where you can learn about the app development process and what elements you need to study. It covers very basic parts, from screen composition to data management and screen transitions.

We'll teach you the true essence of object-oriented programming. Knowing terms and syntax like class, object, self, super(), and interface doesn't mean you understand object-oriented programming. Object-oriented programming is not simply a collection of syntax, but rather a philosophy on how to solve the problems of increasingly complex software. You can only use it properly when you understand the history and philosophy behind it. In this course, we first explain what problems object-oriented programming was created to solve, and what kind of thinking and design philosophy it embodies, independent of any specific language. Then, using Python as a tool, we gradually cover through hands-on practice how object-oriented concepts are designed and implemented in actual code. Through this course, you'll gain not object-oriented programming that merely follows syntax, but object-oriented programming that you can think through and design, and object-oriented thinking skills that remain solid even when the language changes.

You will thoroughly understand the principles!

This course is for those whose coding skills are as fragile as a sunfish. Come listen to a lecture with a "young sunfish" mentality—calm, yet anything but!

This course provides a complete introduction to programming with Python. You will start from the very basics and gradually build up to writing more advanced scripts and solving real-world coding challenges. With step-by-step explanations, practical exercises, and projects, this course is perfect for anyone looking to start their coding journey or strengthen their foundation in Python.

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.

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.

From small projects to practicing structure building! A hands-on, mini-project-based introductory course for those who lack experience in Java object-oriented design and practice. From the basics to structural thinking, improve your skills by implementing a Java application from start to finish.

This course is for anyone who is curious about developing test automation on Android and iOS devices. This course will enable you to perform automated testing on mobile devices.

Do you manually type in numerous commands every time you build a complex project or create a deployment package? Currently, most open-source projects use build automation scripts to save the trouble of typing commands. Do you also find building tedious? Then use this course to automate your builds and increase your work efficiency.

This course is beneficial for those who wish to learn how to use ChatGPT and acquire basic Python grammar. It's also helpful for individuals looking to learn and consolidate basic Python grammar.

"Automating your work? Who doesn't know what's good for them?" You don't need to use a knife to catch a chicken. I want to show you that 10 lines of simple code are more practical than complex crawlers on the Internet.

This course is a process of learning the basic theories of data structures by directly implementing them using JAVA programming. It is designed to go beyond simply learning theory, allowing you to gain a deeper understanding of the principles of data structures by implementing them with actual code. Learners will theoretically study core data structure concepts such as arrays, stacks, queues, lists, trees, and graphs, while simultaneously experiencing the actual operation process by implementing them in JAVA code. Through this, you can develop logical thinking and problem-solving skills rather than simple rote learning, and enjoy the synergistic effect of mastering both programming and data structures together. 👉 Upon completing this course, learners will master the basic concepts and structural characteristics of data structures, as well as the ability to implement and apply them in real-world development environments, building a foundation for designing more efficient and robust programs.

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.

For those who want to learn data science, big data, and web crawling, (1) we summarize the most essential Python syntax in a short time, and (2) you'll become familiar with Python and crawling through practical crawling programming.

This course is a video lecture that systematically covers the core modern JavaScript syntax essential for learning React.js and Vue.js frontend development. It is structured to help you develop efficient coding skills through ES6+ syntax, latest features, and practical examples that can be directly applied to work and learning.

Software development roles in the defense industry: ✔ Have different hiring criteria compared to general IT companies ✔ Use specialized tech stacks and development methodologies ✔ Offer very little information on how to effectively highlight your major, career, and projects. This course: 👉 Provides the perspective of a software developer who has experienced actual defense projects and hiring processes 👉 Explains how defense companies evaluate software developers 👉 Focuses on specific case studies to show you how to prepare your resume, interviews, and projects to increase your chances of success. This course transforms the state of "wanting to become a defense software developer but having no idea what to prepare" into a "clear roadmap you can start following right now."

This course focuses on developing immediately applicable visualization skills by utilizing Seaborn, a core tool for data visualization, and Plotly/Dash for building interactive dashboards.
