We will show you how Java backend developers using IntelliJ can maximize their productivity with Claude Code. In particular, we help you perfectly resolve the vibe coding environment issues faced by those using Windows environments.

Learn how to easily integrate the ChatGPT API using Spring AI and develop an AI server through prompt engineering!!

Drawing from my own experience of feeling despondent when trying to implement practical code during my first MSA transition—despite knowing the theory—I will help you grow into a developer who guarantees perfect data consistency amidst any system failure by directly rolling back daunting compensation logic through 9-step practical patterns and AI Agent coding.

We invite you to the fascinating world of coding where you analyze and visualize financial statements using only prompts. Without a single line of code, you create and deploy a service in consultation with AI.

Spring CRUD Starting with the Price of Chicken Start server development with the price of chicken!

This is a practical course covering how to build systems robust against failures. From design fundamentals for service stability, various patterns to prevent failure propagation, asynchronous processing using message queues, to strategies for maintaining distributed data consistency, you will learn the core technologies and concepts required for a stable backend system.

Even without knowing a single line of code, deploy the idea you came up with today as a working web service today. A hands-on course that takes you through planning, design, functionality, data, and deployment all at once with Google Antigravity.

An AI system that grades and reviews your code in just 5 seconds—imagination becomes reality. This course is an all-in-one project curriculum for creating a **'GitHub PR Auto-Analysis and Grading Bot'** using Spring AI. When a student submits an assignment (Pull Request), the server detects it, and the AI analyzes the code changes (Diff). The grading results are then stored in a database, feedback is automatically posted as a GitHub comment, and the student can check their results on a dedicated dashboard. From backend to AI integration and frontend (Vaadin), all with just Java! This is the ultimate introductory guide for any developer who wants to build their own AI service from A to Z.

Let's create a service that improves itself even while you sleep! Learn step-by-step how to build a 24-hour vibe coding system using loop engineering with Codex.

Even non-developers and marketers with no coding experience can use “vibe coding” technology to verbally explain their ideas to AI and create practical campaign pages and mockups themselves. This completely eliminates the workflow bottleneck of having to wait a week at a time for feedback and development schedules from the development team after writing a project proposal, enabling them to complete fully functional pages on the spot through conversation alone during meetings. Furthermore, they can easily build survey apps where user responses actually work and are saved, along with integrated databases, then deploy them to real URLs and share them with team members and customers with one click to validate ideas at lightning speed.

The most definitive practical guide for developers who want to integrate AI into their Spring projects right away! Beyond simple LLM API calls, you will perfectly master building production-level AI environments that can be immediately applied to real business logic using RAG and MCP.

Key Practical Features for 6 MS365 Tools Updated with Copilot From Excel, Word, PowerPoint, Outlook, OneNote, to Teams, will your proficiency in the tools you use daily at work suddenly level up with Copilot? Even without OA classes that require significant time to memorize each function, you can easily obtain the necessary results with the help of Copilot, your personal work assistant. This course begins with the concept and basic usage of Copilot, then guides you through functions that can maximize work efficiency by utilizing Copilot according to your workflow, from meetings to document creation, analysis, and presentations. You can immediately apply the customized prompts for each tool, provided by an MS365 MVP expert, to your practical work.

From coding basics to launching your own app all at once?! The App Build All-in-One, connecting fundamentals and practical application.

Don't memorize commands. Just say, "Do this." Even without programming experience, let's have Claude Code perform 5 tasks. From file organization and document writing to data analysis, automation, and even web pages. The only payment required for this course is Claude Pro ($20/month). All other tools used are free.

This course is for those who don't know much about development but want to start "vibe coding," and for those who want to personally create a landing page to promote their own business (restaurant, cafe, etc.) or service (lawyer, accountant, hospital, etc.). I will help you establish the perfect starting point for vibe coding.

Let's begin developing with Copilot (copilot). With AI, even elementary school students can follow along!

This course teaches non-developers how to properly build, operate, and monetize a service using Claude Code. It provides template repositories and operational know-how so that non-developers and beginner developers alike can use Claude Code at the level of the top 1% of developers. This course will be especially helpful for those who want to build a service with Claude Code at a truly “professional developer” level; those who want to create a service capable of generating revenue through a one-person business or side project; those who have built something powered by an AI agent like Claude Code but are stuck because they lack the know-how to operate it properly; and those who feel overwhelmed as their solo project grows because bugs keep occurring and things become difficult to control whenever they add new features. The course also covers how to build a foundation for monetization and provides guidance on operating the service under the assumption that real customers will be using it. Once you have actual customers, processes such as monitoring errors occurring on the production server, server status, and logs are essential. However, there are surprisingly few places that teach these processes. In my course, along with this kind of detailed and professional operational know-how, I also explain how to enable AI to observe these monitoring metrics and data and take appropriate action.

"The cost of making one app is the price of a cup of coffee." Learn vibe coding with Kimi K3, an open-weight model with 2.8 trillion parameters. You’ll launch your first app in a browser with a single sentence, create a UI by providing a hand-drawn sketch, and have it build and deploy an entire full-stack web app to the internet. If you’re already using Claude Code, you’ll also learn how to keep that environment as-is and simply switch the model to K3. It’s pay-as-you-go, not a monthly subscription. In an actual test, one session that created and deployed an app cost 1.69 dollars. 14 lessons, approximately 102 minutes total; the course is free.

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