What you will gain after the course

  • Step-by-step practical guide to making up to 5 million won per month through private tutoring

  • How to guarantee earnings even for those who are tutoring for the first time

  • Essential principles and know-how you must know to generate profit

💵 Don't you want to make a lot of money with a side hustle?!


"Haven't you ever wanted to generate income through a side hustle?"

"Isn't your salary not enough on its own?"

"Side hustles are something you want to try, but how to do them is what you're unsure about?"

"You started a side hustle but money isn't coming in?"


Something I have never mentioned anywhere else

applicable to most side hustles

The general principles and formulas for generating profit are all included in this lecture.

In particular, I will teach you in detail how to generate revenue using mentoring and tutoring.



👋 Hello! I am...

Hello, I am Jaeseong Park of JSCODE, who earned up to 10 million won per month through tutoring/mentoring at the age of 30.

Currently, I am active as a knowledge sharer on Inflearn (with 32,000 cumulative students as of March 2026).


I wasn't a developer from the so-called "Na-Ka-Ra-Ku-Bae" (Naver, Kakao, Line, Coupang, Baemin) companies either,

I didn't graduate from a prestigious university like SKY, either,

I was an ordinary developer from a non-major background who didn't even study computer science.

My credentials weren't particularly flashy or impressive,

I wasn't a professional tutor, either.


So, when I first tried to start tutoring,

'Would anyone even want to take a class from me?' was the very first worry that came to my mind.

In fact, when I first posted an advertisement for tutoring,

I even received a malicious comment saying, 'Who would pay that much to learn from someone with your specs?'


These are the things I have actually achieved.

Achieved 10 million won in monthly sales through tutoring

Achieved cumulative sales of approximately 100 million won or more through tutoring

More than 100 cumulative students

Maximum number of students in a single month: 20 people

Kakao Pay, Yanolja, Woowa Brothers produced successful applicants

If you also use the right method,

If you put in the time and effort

These are results that you can certainly achieve.



🔄 We even teach you things like this!

What many tutors worry about is

They say that students quit after only about 1 to 2 months of lessons.


On the other hand, students who have taken my class even once

Why do they not quit halfway through and stay until they get a job?

Why is it that they only want to take classes from me?


Even after the classes are completely over and they have successfully found employment,

Students constantly send me KakaoTalk messages to say hello and express their gratitude.


I don't just finish the class as a simple business relationship,

I strive to conduct classes that are enjoyable and allow for deep interaction between myself as the teacher and the students.


So, in this lecture, by turning students into my true fans,

I also plan to share methods to keep students re-enrolling continuously.




4 Points I focused on while creating this course

I tried my best not to include cliché know-how that can be easily found by searching on Naver or Google. Instead, I focused on including insights I gained through my own direct experience that cannot be easily learned elsewhere.

I believed that if you cannot apply what you've learned in practice even after completing the course, then it is a flawed lecture. I tried to focus on know-how that can be applied immediately in the field, rather than an academic approach of deeply studying only the theories related to side hustles.

I thought it would be a flawed lecture if it only taught content applicable to a tiny minority of people. Therefore, I tried to structure this lecture focusing on know-how that even ordinary people can utilize.

I have included methods for generating income through tutoring and mentoring even with ordinary credentials. I also started tutoring without any exceptional background. I have packed all of that know-how into this lecture.

💁‍♂️ "What if it doesn't work even after I do exactly as the lecture taught me?"

The part I worry about the most while creating a lecture is

'What if the students are dissatisfied after taking this course?' is my biggest concern.

As a teacher who instructs others myself,

I feel a sense of pride when the content I've taught actually proves helpful to the students.

If my lecture hasn't been of any help to someone at all

I would feel just as uncomfortable and apologetic.


That is why, for those of you taking this course,

In the hope that you will receive meaningful help,

I have opened a 1:1 open chat room so that you can ask questions whenever you are curious or feel stuck.


Even though you followed the methods I taught in the lecture,

If you are not generating profits, please do not hesitate to

please request help through the 1:1 open chat room.

I will do my best to support you by your side so that you can generate profits💪



🚫 I recommend that these types of people do not take this course.

This course is not about teaching you how to make a lot of money with very little time investment.

What I've felt while trying various types of monetization so far is that

Most things that allow you to work little and earn a lot of money are either unrealistic or

often turned out to be scams.


If there are any among you currently reading this course introduction who

If you are someone looking for a jackpot by investing only a little bit of time

Please do not purchase this course.


I don't know of any way to work a little and earn a lot of money.

But as long as you put in the sincere effort

If you are someone who wants to increase your profits step by step,

this lecture will definitely be of help to you.

            I had only been thinking about starting a side hustle without knowing what to do, but after listening to the lecture, I have a much better idea now. Thank you.
