kslj82586229's honest review, Practical Financial Backend Engineering from a Toss Developer Serving 30 Million MAU: Outbox, Idempotency, and Dual Write course

Rather than providing a broad overview, the course focuses on explaining the issues that come up as you implement things step by step. Because of that, it can be difficult to understand the overall structure, and I think you’ll need to review some of the code on your own as you go. I also think it helps to have at least a basic understanding of blockchain. The instructor said the problems aren’t specific to the blockchain domain, but the code does assume a blockchain context, so it’s important to pay attention to the small explanations given along the way. Even so, I’m quite satisfied with the content itself. It was a good fit for me because the approach was similar to the way I like to study. Thank you for the great course!
