We'll complete one full cycle of a backend service using Spring Boot, MySQL, Docker, AWS EC2, and RDS. You'll gain a sense of accomplishment through application deployment, and learn about the problems server developers face in real-world API development and their solutions.

Learn SAGA transaction management techniques for maintaining data consistency in distributed environments through hands-on practice. Build 3 microservices using Spring Boot and Docker, and implement both Orchestration and Choreography patterns with Kafka and MySQL. Through this course, you can master core concepts that are immediately applicable in real-world scenarios, including distributed transaction operation principles, compensating transaction design, and failure recovery handling.

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.

With the price of a chicken combo, you'll learn the deployment process in order: Spring Boot manual deployment -> Docker deployment -> Github Action CI/CD!

From Docker, Kubernetes to microservices, CI/CD, and service mesh, you can easily learn not only the basic theory but also the actual application implementation through examples. By organizing only the core contents necessary for actual use, it provides a starting point for learning about the element technologies covered in the lecture.

Learning about various communication techniques and understanding their differences helps you develop the ability to select and implement the most appropriate communication method.

AI is no longer a choice, but a matter of survival. Reduce development that took 3 days to 30 minutes, delegate repetitive tasks to AI, and focus on solving more important problems. With AI-native development methods that you can apply immediately in real work, not just theory, we'll show you the definitive way to be recognized as a "developer who's good at AI" at your company.

This course proceeds in stages, similar to the actual work, by learning and applying the necessary knowledge while configuring the infrastructure.

Did you give up while studying Spring? Even complete beginners new to coding and non-majors can make it from JSP to Spring Boot without giving up - we'll open the path to Spring Boot for you.

A practical course on easily building a super simple bulletin board with Spring Boot and React.js! This course focuses less on theory and more on hands-on practice, covering the web application development process for quick completion.

🔥 From course registration to video uploads, this is a hands-on full-stack course that implements knowledge creator features just like the real thing. Using Next.js 15 and NestJS, you'll build course creation, curriculum composition, thumbnail and video uploads, and detailed description writing following the actual Inflearn workflow, gaining near-professional experience with Prisma modeling, JWT authentication, S3 + CloudFront uploads, Swagger API design, and more.

Build a local LLM with RAG-based Q&A system in just 2 hours of hands-on practice using Docker + ollama + R2R framework. (Suitable for in-house/internal Q&A systems, personal portfolios, AI-powered work capabilities, and even commercial services)

This is a full-stack restaurant map tutorial that allows you to learn everything from front-end, back-end, Kakao Map API usage, and deployment all at once while creating a restaurant map of your favorite YouTuber.

This course is a complete, hands-on Git and GitHub masterclass designed to help students master version control from the ground up. Through years of working with Git in real-world projects and helping learners overcome common Git frustrations—such as merge conflicts, broken histories, and collaboration issues—I’ve designed this course to be clear, structured, and practical. Each concept is explained step by step, followed by real examples and workflows used by professional developers. Whether you are working alone or in a team, you will learn how Git really works, not just commands to memorize. By the end of the course, you will confidently manage repositories, collaborate using GitHub, and maintain a clean, professional project history.

The hottest vibe coding these days! You can learn how to develop and deploy a website (Next.js) with just a click using AI tools. We'll even show you how to develop for free using Google Gemini Pro.

I highly recommend Spring AI to developers using Spring Boot and React, as well as those considering the introduction of AI systems in corporate environments. This course goes beyond a simple introduction to libraries; it helps you understand the core concepts and internal structure of Spring AI, and strengthens your practical implementation skills through various hands-on examples. The course is based on Spring AI version 1.1.x and provides continuous technical support and expansion strategies to ensure you can adapt to future version upgrades. Furthermore, we expand the practical value of Spring AI technology by utilizing MCP (Model Context Protocol) to achieve cross-domain context integration, AI linkage in distributed environments, and AI architecture design suitable for enterprise environments. With the goal of building AI systems that can actually be deployed in corporate settings, this will serve as a practical guide that balances theory and hands-on experience.

This course is an introductory coding program for non-developers, aiming to eliminate vague fears about coding and instill the confidence to directly build web services and applications.
