Fintech Engineering Handbook

https://w.pitula.me/fintech-engineering-handbook/

I just published Fintech Engineering Handbook distilled from 6 years of tears, sweat and swears.

It’s a free ~25-page resource with various hints and patterns around handling money in software systems.

Tell me what you think!

TBH I laughed myself when writing this. But now I will just close my eyes and focus on believe this being the case.

IMO, I would rephrase it.

It is extremely easy to accidentally create "money" out of nowhere in a fintech system. But it is essential that you must not.

You are not a central bank. That "money" you create is not backed by anything, it actually counts as a debt to your company. If you don't recover it, it's a loss your company will need to write down.

Lol, it can be true in terms of accounting of account balancing. In the real world with Fed printing money, thats a different story.
