Create your own API server without coding with Strapi

Instead of long and boring theories, you can learn them one by one through short practical exercises, and as you flesh them out one by one, you will soon be able to experience the overall architecture composition.

After learning SQL tuning, automate recurring tuning tasks. This hands-on project connects everything from collecting MySQL queries to AI diagnosis, empirical validation, handoff to the person in charge, and tracking recurrence.

We will learn how to create a system to support large amounts of data and traffic by creating it directly with Spring Boot.

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.

I've created a cram course that will help you pass the AWS SAA-C03 (AWS Certified Solutions Architect - Associate) certification in just 2 weeks with only 163 questions!

How can you withstand skyrocketing traffic? Learn how to build a resilient and flexibly scalable architecture through practical design patterns based on EDA (Event-Driven Architecture) using Kafka, Spring, CDC, and Temporal. Explained clearly and simply—even for non-majors—alongside the real-world experience of a Kakao developer. A hands-on course covering everything from real-time data flows and event processing to microservice integration!

From the fundamentals of MySQL usage to the advanced techniques required in real-world service environments, you will learn progressively. The course also covers a wide range of topics, including data modeling techniques based on various cases and practical data, evaluating the effectiveness of Foreign Key design, analyzing the Google Calendar schema DDL, and modern DDL design principles. It provides an in-depth understanding of how to use MySQL as a core component of a system, rather than merely as a database.

We will apply it in practice by crawling sites such as Naver, Amazon, Twitter, YouTube, Facebook, Instagram, and unsplash.com.

This is a course that has been moved to Inflearn for easy learning through the agreement of the original author of Life Coding. I would like to express my gratitude to Life Coding http://opentutorials.org.

This course focuses more on data modeling through entity design than on JPA technical explanations. Based on the principle that solid DB design is the foundation of application development, we analyze various design patterns—such as one-to-many, many-to-many, inheritance, and collections—alongside business scenarios. You will learn by directly observing the process of code being transformed into actual tables on screen. To ensure immediate practical application, we provide business use cases, source code, and test codes for each design pattern.

This course proceeds in stages where you learn and apply necessary knowledge while building infrastructure, similar to real-world practice.

This course is designed for those who are new to Debezium-based CDC and unsure where to begin. You will gain hands-on experience with the entire process of collecting MySQL change data in real time via Kafka and delivering it to PostgreSQL. By learning everything from the basic principles of CDC to configuration and operational best practices, you will be able to build real-time data pipelines on your own.

‘Where and how should I store files that look like images? Should I store them in a database? Or on a server hard drive? How can I reduce server load? How can I quickly load many images without stuttering? AWS S3? CDN?! I just want to store and load images, so why are there so many elements? What role do each of these elements play, and how should they be combined?’ I will teach you all the necessary elements related to image files, from start to finish, as a full stack :)

A 30-minute free introductory course that starts with just the OpenAI API. Quickly learn the essentials—from the Responses API and JSON response handling to validation, idempotency, and logs—and learn a practical backend workflow that you can test right away without external service keys.

This is an advanced course on map service development, taught by the developer of CoronaMap.

This is a practical course where you can learn the process of building a company website yourself using React, Node.js, and MongoDB. Let's build a full-stack project together with a basic background in React and Node.js!

This course goes beyond basic CRUD-level database usage, helping you develop the PostgreSQL skills needed in the AI era from a practical, real-world perspective. Drawing on AI development experience in Silicon Valley, you’ll gradually learn how to design and use JSON, indexes, transactions, and pgvector in actual services, while gaining the skills to solve complex data structure and performance problems.
