achoi68339754's honest review, Practical Financial Backend Engineering from a Toss Developer Serving 30 Million MAU: Outbox, Idempotency, and Dual Write course

Hong said this directly during the live session: "Don’t let AI undermine your confidence. Become someone who can make use of AI itself." From that perspective, I found this course really useful haha. Before taking this course, I think I would have asked AI something like: - "Create an order API that processes payments by integrating with a payment gateway." But thanks to what I learned in this course, I’ve grown and learned more, so now I think I could ask something like: - "I’m going to integrate with a payment gateway, so make sure to handle retries and idempotency. I want to guard against duplicate payouts. Also, ~~ are things I need to consider from the perspective of an external domain (blockchain in this course), so please take that perspective into account too." I feel like I’ve become someone who can put together questions in a more structured way haha. Thank you for the great content!
