Solving asynchronous architecture using RabbitMQ in one go

This is a course where you can experience a comprehensive list of questions and answer directions for technical interviews and personality interviews. In particular, the course is structured to help you prepare for interviews by learning through questions and answers about server scaling strategies and large-scale data processing strategies that junior-level candidates must know for technical interviews, as well as how to provide the best answers to questions without definitive answers that you encounter in final interviews.

This is a career guide course that summarizes everything you need to prepare for getting a developer job or changing jobs, including resume, portfolio, technical interview, and behavioral interview, all in one place. In the theory section, we've organized the process of finding the right company for you, analyzing job postings, and preparing for interviews and coding tests.

After verifying the issues resolved by Spring Boot auto-configuration, we come to realize that unless there's a specific reason, we should develop to integrate with Spring Boot auto-configuration!

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!

I have created an 'Introduction to Elasticsearch' course that is easy for non-majors to understand and can be applied immediately in practice!

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.

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.
