I'm running a year-end event on my YouTube channel.
Hello students.
I'm Choi Ho-seong, the laid-back developer.
Another year is coming to a close. As always, I'm wrapping up an eventful year and preparing to welcome the new year. While we can't know the future, I think it's good to have hope for the coming new year. 😄
In that spirit, I'm running various events (50~100% discount coupons) on my YouTube channel (https://www.youtube.com/@nullnull_not_eq_null). To participate in the event, simply leave a comment on the video linked below. When leaving a comment, choose the course you want from my courses and request a coupon. Once I see your comment, I'll reply with a coupon. The discount rate is random. 😄

This could be an even better choice than Black Friday discounts. Therefore, I recommend that you watch the video and participate. By watching the video, you can also learn how to take three courses for free, so please be sure to watch it and participate in the event.
Thank you as always. 😄
From NullNull Developer
