Practical! Spring Data JPA
Spring Data JPA goes beyond the limitations of the past and allows you to complete development with just an interface, without implementing classes in the repository, as if by magic. It also provides all the basic CRUD functions that have been developed repeatedly. We will share practical know-how on Spring Data JPA.
I have news to share with you all - a new challenge
Hello everyone. This is Kim Young-han.
I have decided to leave Woowa Brothers, where I have enjoyed working for the past 7 years, and take on a new challenge for the growth and education of developers.
First, let me tell you why I made this choice.
It's been about 4 years since I started teaching online technologies like Java, Spring, and JPA for developers at Infraon. During that time, I've received many reviews and emails like the following.
"I was not a major so I didn't know how to study development, but after listening to Younghan's lecture, I passed the Nekaraku Cup."
"While working at SI, I thought about quitting my job as a developer because I couldn't see a path for growth, but after listening to Younghan's lecture, I saw a path. So I listened to the roadmap diligently and prepared, and was able to get into the mid-sized company I wanted to go to."
"I work for a small company and don't have a salesperson, but through Younghan's lectures, I was able to find a way to study and grow."
I also heard the following story a lot from people around me.
“If you look at developers applying to companies these days, they have a good grasp of the basics of technologies like Spring and JPA, and most of them have taken Younghan’s lectures.”
“When I look at the junior developers on our team, most of them study by listening to Younghan’s lectures.”
“I was worried about junior developer training, but I recommend Younghan’s lecture. Thanks to him, I am less worried about training.”
I graduated from high school and had a hard time getting a job as a developer. When I was a junior, I worked in a bad environment and felt like my life was covered with thick fog. At that time, I thought it would be great if someone could give me direction for my development. That's why I feel a great sense of accomplishment when I see someone's life changing and growing into a good developer thanks to the lectures I prepared. In particular, I heard a lot of good stories like the one I just mentioned last year. I think the developers who studied hard are now reaping the fruits of their labor.
As I listened to my lectures and saw many developers grow and change their lives, I thought deeply for the past year. The reason I thought so long was because working as a technical director at Woowa Brothers and developing the Baedal Minjok service with the members was so enjoyable and exciting for me. And fortunately, I had the experience of leading and improving a good service that was growing rapidly, and at the center of it, I was able to design and develop various domains such as payment, settlement, order, exhibition, and common platform, and also experience improving the entire service to a microservice architecture with the members.
People may have different thoughts on what kind of life is more valuable, but I thought deeply about what I am doing at this point in time that is more valuable and meaningful. It is meaningful for me to grow and fill myself through my work, but I thought it was more meaningful at this point in time to make it easy for anyone to learn the numerous practical development know-hows that I have pondered and experienced for a long time. I hope that through this, the next generation of developers will grow quickly and become better developers than the current generation of developers. Therefore, I plan to do the following things in the future to help developers find jobs and grow.
1. Developer Employment: For those who want to become developers, we plan to complete a lecture curriculum that will allow them to learn everything they need online (Infraun). We will start with basic lectures such as Java and database design.
2. Developer Growth: I plan to create high-level practical lectures so that practical developers can grow further. I want to help practical developers easily learn and apply the practical experience and wisdom I have gained so far, such as testing, development architecture, MSA, design, etc. So I want to raise the technical capabilities of the entire development market.
I feel grateful and sorry to the members of Woowa Brothers who have been with me for the past 7 years. However, I am truly grateful that everyone supported and cheered me on when I made this decision.
I sincerely thank all the developers who attended my lectures at Infraon and supported me. I believe that each and every one of your support has added value and meaning to my life.
thank you
