Ju-Ho Yoon's honest review, Learning OpenAI Codex through Projects - From Basics to Advanced Vibe Coding Using AI course

For those who have been developing for a long time or are already familiar with using AI, this may feel somewhat basic. However, it consists of various hands-on projects using Codex, including a Funding Fee dashboard for a cryptocurrency exchange, so it would be a good course for those interested in this field. Rather than focusing on technical aspects, it seems to cover only the essentials of vibe coding, with the key being how you apply and incorporate the instructor’s know-how. If you are already familiar with the subject, it may be a good idea to skip the earlier sections and start with the hands-on exercises. I felt this course would be especially suitable for those who are encountering practice environments such as Codex App, Codex Cloud, and Codex CLI for the first time and want to become familiar with them through hands-on work. It also includes practical sections on automating office tasks and using Codex App Server, so I would recommend it to those who are just starting to learn programming and want to develop a feel for it through practice.
