3. Web Development Course [Enterprise Architecture (EA) X E-Government Framework]

Learn deep learning through PyTorch. Ultimately, the course covers image classification.

Let's learn the C# language. You can learn it even if you don't know the C language. The development tools are also installed from the beginning.

You can learn how to solve concurrency problems, how to tune procedures, and how to speed up query execution. You can also learn various know-hows such as common mistakes and problems that occur in practice. (The only refactoring lecture in the world)

This is a class on MSSQL, one of the three major databases. Even if you are learning databases for the first time, you can learn it easily.

Learn how to save, modify, delete, and query data in a database. Anyone, regardless of major, can easily follow along in just 30 minutes.

JAVA is a programming language, just like the C language. JAVA can be used for web development and application development, and here we will learn JAVA before doing web development.

This is a lecture using the only domestic e-government framework and Layered Architecture, which are widely used in practice but not available in Korea. In this lecture, we will learn how to build the backend and server side of web development using the Spring Framework and the e-government standard framework.

Hello. I have prepared a lecture on HTML, which creates the frame of a web page, and CSS, which decorates the web page. It is the most basic before web development, and it is prepared so that even beginners can learn it easily.

You can solve design problems by writing code in a formatted way. You can understand code or patterns written by other programmers.

Creating an application on Linux (Ubuntu OS). (Cross-platform application development)

We will cover ASP.NET Core Identity, creating bulletin boards, EF Core, data filtering, etc.

Learn C# for developing applications like ASP.NET, Winform, WPF, and MAUI that run on the .NET Platform.

This course teaches you how to communicate in real-time with ASP.NET Core, MAUI, and WPF using SignalR.

We cover ASP.NET Core, which is mainly used by foreign companies and large corporations.

Learn about MAUI cross-platform development, which lets you develop and run Windows, macOS, iOS, and Android applications with a single code base.

SSIS, SSAS, MachineLearning, BI, ETL. You can learn important technologies that cannot be found in domestic books, YouTube, lectures, blogs, and academies. I also recommend it to those who are interested in employment at domestic large companies, American large companies, and American state funding agencies.

In this lecture, you will learn how to create an ERD. You will learn database design. (The only big data design lecture in Korea)

This is a class diagram lecture in UML. This is a design lecture.

This is a WPF lecture that will be helpful to developers who are considering introducing WPF in WinForms, application developers who are hoping to get a job in the US, and those who are hoping to get a job as a developer. It is not a lecture focused on theory and design, but covers content that can be used in practice.

This is a course to learn MariaDB, a commercially available database. Even if you are learning about databases for the first time, you can learn it easily.

This is a lecture using the only domestic e-government framework and Layered Architecture, which are widely used in practice but not available in Korea. In this lecture, we will learn how to build the backend and server side of web development using the Spring Framework and the e-government standard framework.

This is an introductory backend development course where you learn through understanding rather than memorization, and experience rather than theory. Instead of reciting a Googled definition when asked "What is JPA?" in an interview, this course will empower you to give an answer based on experience, starting with "Well, I've been through JdbcTemplate hell..." You will gain a deep, intuitive understanding of "why we use frameworks" by experiencing firsthand how 30 lines of pure Java ServerSocket code shrink down to just 7 lines in Spring Boot. After 6 sessions, you will walk away with a functional portfolio piece: a Todo List REST API built with Spring Boot + JPA.

Practical Payment System Development Course, learn by code, and cover the knowledge needed to implement a real system.

Based on an understanding of Reflection and Annotations, it helps you clearly understand how the Spring framework operates!

Hello. I have prepared a lecture on HTML, which creates the frame of a web page, and CSS, which decorates the web page. It is the most basic before web development, and it is prepared so that even beginners can learn it easily.

JAVA is a programming language, just like the C language. JAVA can be used for web development and application development, and here we will learn JAVA before doing web development.

"The Era of Coding with AI: A New Productivity Paradigm for Java Developers" This course is a practical Cursor AI utilization guide for Java developers. Beyond simply copying AI-generated code, you'll learn Vibe Coding methods that maximize development efficiency through collaboration with AI. By leveraging Cursor's powerful code understanding, refactoring, and documentation features, you'll master AI coding workflows step by step that can be immediately applied to real-world projects. In an era where AI writes code for us, "developers who can effectively work with AI" now have the competitive edge. Start your upgraded development experience as a Java developer with this course.

In this course, rather than directly covering theory, you will learn how to effectively use Redis in code through hands-on practice.

Understand the basics of the e-Government Standard Framework and the Korea Government Design System (KRDS), and proceed with the redesign of the Military Manpower Administration website using the Korea Government Design System (KRDS).

This course is a practical program where you will master Kotlin-based AI agent development by building your own coding agents. Using Koog, an AI framework built with Kotlin, you will learn step-by-step how to implement coding agents similar to Claude Code, Cursor, and Junie. Koog is more than just a simple server-side framework; it integrates seamlessly with Spring and offers the scalability to connect with various environments—including Android, iOS, Desktop, and Web—through Kotlin Multiplatform (KMP). By building intelligent agents that can read, analyze, modify, and generate code, you will gain hands-on experience in AI agent architecture, strategy, context handling, and tool integration.

Have you ever wondered "how" the many Java libraries and frameworks you use provide this functionality? In this course, learn how to manipulate various codes or objects provided by Java and take your Java skills to the next level.

IntelliJ IDEA Conf 2025 is an annual online conference hosted by JetBrains that provides valuable sessions for Java and Kotlin developers. It covers various topics including AI adoption, Spring Boot, Gradle, Kafka, database management, and also shares insights on cloud integration, secure coding, developer performance improvement, and advanced development techniques. This conference is open to both professional and beginner developers, offering opportunities to explore the latest technologies along with productivity tips for writing high-quality code faster.
