Work Automation AI Agent Ready for Immediate Use in Companies (w. n8n, LangGraph)

The process of directly seeing how the shallow knowledge of artificial intelligence I learned during my undergraduate years could be applied in practical work was extremely interesting. In particular, I was able to gain many ideas through the lectures and tried to apply them immediately. Recently, at a hackathon, there was a task where I needed to generate different random topics for 40 teams. What would have taken a long time if done manually was completed in just 20 minutes thanks to the AI agent. That moment was truly thrilling. Also, I really appreciated how Byungjin showed the process of solving problems when errors occurred during the lectures. Rather than simply providing the correct answers, I was able to gain great insights by watching the process of analyzing problems and finding solutions. I feel like I'm experiencing firsthand the tremendous benefits that come from automation!

I urgently needed to create a POC for a RAG project that came up suddenly, and while looking for suitable lectures, I tried a preview lecture and immediately purchased the roadmap. I quickly went through it once without hands-on practice, just to skim through the concepts. Since I started using cloud code, I felt like I could build anything on my own. Now I truly feel like I can build anything. The project contract cost (with the project contract being certain if I just create a good POC) is hundreds of times more than the instructor's roadmap cost - I don't know where else you can find such cost-effectiveness. Here are the lecture advantages I experienced: 1. Clear pronunciation and good delivery. 2. It's realistic because it contains processes with mistakes/typos rather than being a perfect lecture without any errors. 3. References documents including papers are mentioned. 4. Introduces various tips that can only be known through actual work experience (line breaks in pdf parsing/prompt writing/table and image processing...). 5. English pronunciation isn't strange? (Many instructors pronounce basic English words ridiculously, which was often bothersome, but there were no such cases here) 6. Important concepts are repeated dozens of times. You'll understand eventually. When I first listened to the LangGraph lecture and heard mentions of edge/node/state, I wondered what it was about. But just watching the same process being created hundreds of times, I think I roughly understand it now. I usually don't leave course reviews, but I strongly recommend this for those learning langchain/langgraph/rag.

The fast-paced progression (though I am watching at 1.2x speed) and this feeling like a mentor at work is sharing only the essential gems! It's exciting and great! 😆

It was very helpful when using it for actual work because it explains the process of creating real results rather than just simple knowledge learning.

I came to the n8n course after taking Byungjin's langchain and langgraph courses. Definitely, after taking the previous courses and then listening to n8n, I understand the concepts better, and it suddenly feels easier since there's no code😊😊 Thank you for the course!

I can follow along step by step and the explanations are clear. I think I'll be able to use this for automation tasks.

What started as curiosity-driven listening to your lectures has now led me to work on internal company projects. Thank you for providing such high-quality lectures. I will diligently listen to and study the remaining lectures (plus any new ones that come up)!

The pace is so fast, I love it. 😭😭 I can always search and study the parts that are quickly skipped over on my own.
