Introduction to Spring Batch: Fundamentals of Large-Scale Processing in 3 Hours

🥵 I'm... the Spring Batch lead...?

I am JSCODE Sini, who started as a developer and has produced over 200 developers while working as a bootcamp instructor for 5 years.

When I was a junior developer, I suddenly became the person in charge of managing Spring Batch at my team leader's direction. I was hired and working as a backend developer, but in reality, I had never handled or managed Batch before.

Don't we all have experiences like that? I'm just a "talking potato"... and I'm the one in charge? Not wanting to be looked down upon for being incompetent, I opened the Batch code I had to manage. However, perhaps because I had absolutely no concept of Batch, the code felt like an alien language to me.
I remember being afraid to even go to work, fearing that my lack of skill in handling Batch would be exposed.🥶

Thinking "I can't go on like this!", I tried to start studying in earnest. However, it was very difficult to find a suitable book. The few books available were so thick that I felt suffocated before even opening them.
When I looked for lectures, most of them were over 30 or 40 hours long.

It was a daunting situation for me, as I had to study over the weekend and apply it to real-world tasks starting Monday. I even started to wonder, 'Do I really need to know all of this vast information just to handle Batch?'

That's why I created this course, so that those who are new to batch processing, just like I was, can apply it to their practical work in a short period of time.

There is a saying, "Coding once is better than reading a hundred times!" Your skills won't improve just by studying batch concepts for days on end. The fastest way to learn is to implement even a small batch in code yourself and apply it to a real-world project.

The goal of this course is to be a definitive introductory guide for those new to batch processing, enabling you to understand the flow of batch jobs and know how to read and utilize the code in just 3 hours.

I hope you don't have to tremble with anxiety like I did during my junior years. Do you need to apply Batch to a project right away? Have you become a Batch administrator starting today? If so, I hope you can lower your fears and firmly grasp only the core concepts essential for real-world practice through this course.

I'll see you in the lecture. ☺️

What if you have questions while listening to the lecture?

If you have any questions or find something difficult to understand while listening to the lecture, please ask using the Q&A board or the 1:1 open KakaoTalk room!🤩

I will check it quickly and provide an answer.

👩‍💻 There are many practitioners who write good code, but educators who make code easy to understand are rare.

A practitioner is someone who writes good code. However, an educator is someone who ponders day and night about why the code was written that way and how to convey that code to students in the easiest possible way.

There are many masters in the field, but often when you listen to their explanations, they are so difficult that you find yourself tilting your head in confusion. This is because they focus more on listing knowledge than on the weight of education itself. If you receive poor education, the learning process itself becomes painful, eventually leading to undesired results and wasting precious time and opportunities in your life.

I want to be more than just an 'instructor' who transfers skills, but a 'teacher' who contemplates your career and life together with you. The power to transform complex concepts into our own language rather than jargon—that is my pride as an educator. Please look into the path I have walked and my sincerity, and make a careful decision for your precious future.

💚 Introducing myself!

Hello! I'm Sini from JSCODE.
It feels like just yesterday when I was dragged by a friend to a major class in college, but I'm already looking at nearly 10 years since I started developing.

When I first started developing, I dreamed that the programs I created would go out into the world, providing convenience and making a positive impact on many people. However, as time passed, I came to a certain realization.

'Rather than building a service myself, properly training one skilled developer could have a greater and broader impact on the world' was my thought.
If the developers I taught created countless values in their respective positions, that influence would grow exponentially.

With that single mindset, I have trained over 200 developers at bootcamps over the past 5 years.(* Produced successful candidates for Line, Kakao, and Kurly☺)
Watching my students grow in the industry, I felt the power and fulfillment of education with my entire being.

Now, I am looking to meet you in the broader online world, moving beyond the physical space of offline classrooms. This is because I want to share my skills and know-how with more people and help you grow into competent developers who can create further value.

I sincerely hope that this course, which I have prepared with great care, brings a positive change to your life.
