It's like an advanced version of React lectures, so I like it. It's not just simple crud, but it's really good to try a little more things.

I've only taken the first day of the course, but it's so much fun and I've learned so much, so I highly recommend it. The existing clone coding and lectures were so boring and uninteresting that I even fell asleep, but Jeong Jae-nam's lectures, which feel like studying, are so much fun! I highly recommend it, and if you have another chance, I hope you'll make a study-type course similar to this one for juniors who can't move from beginner to intermediate.

Finally, I'm done! First of all, the instructor's voice is so nice. The voice itself is so charming that I'm really drawn to the lecture. And... the lecture is more than I expected. I learned more than I initially aimed for!!
React web service development
GraphQL
React-Query
Firebase
Listen to a lecture that feels vivid and real
Start coding and build an online shopping mall service! 🩳
This course is conducted live with students, so you can quickly find and apply only the content you need right away.
We will show you the process of considering and solving various problems that arise during the development process without filtering them.
Through this lecture, I want to show you that you can somehow complete something even if you just start coding without any preparation.
With this, I hope to give courage to job seekers or juniors who are having difficulty creating something.
The full code is available on GitHub , so please refer to it!

-Junior Front-end Developer-
"When I get stuck while coding, I don't know what to do and I'm at a loss.
Additionally, I would like to practice GraphQL and BFF . "

🔔 Create a shopping mall service through coding that you learn through hands-on experience for 10 days.
You will gain enough knowledge to carry out projects on your own.
You will gain the strength to solve various problems that arise during the project process.
I will generously share with you the various know-how I have gained from 9 years of practical experience .
Whenever I start a project without thinking and run into a problem,
We'll show you how to find a solution using a combination of search, debugging, and guesswork.
Q. I'm curious about the level at which I can take the course.
This course doesn't cover basic React or TypeScript, so you'll need some prior knowledge to successfully complete it. However, other knowledge isn't required; simply listening, thinking, and following along will allow you to acquire the material naturally.
Q. Is theory included in the lecture content?
This video includes information necessary for project progress, as well as real-time answers to questions from participating members during filming. Please note that there is no detailed theoretical explanation beyond this.
Q. Is this lecture content suitable for a portfolio?
Because I've focused solely on development and minimal styling, this course alone won't be enough to create a portfolio-quality piece. However, I believe you'll gain sufficient know-how to tackle new projects.
Q. Is there a special practice environment that I need to prepare for?
While the course focused on MacOS, it also provided some guidance on how to address issues that arise in Windows environments. While Visual Studio Code (VSCode) was used as the IDE, you are perfectly welcome to use any other development tool.
Who is this course right for?
I am a front-end job seeker who has learned React but is at a loss when it comes to actually working on a project on my own.
A junior front-end developer who feels limited in project progress due to lack of back-end knowledge
Front-end developers and job seekers who want to practice GraphQL/BFF
Need to know before starting?
