What technical topics can be pulled up for fintech?

Question

Fintech

I want to delve into the development of fintech, the topic is very interesting for me. Please tell me what topics can be studied in order to feel confident in this matter?

I see the following areas:
1. Mathematics.
2. Security of web applications.
3. Working with transactions.
4. Architecture of Enterprise systems.

I asked a similar question before, but this one is less specific. I am also interested in topics related to fintech.

Answer 1

type 2 and 3, but you can just google IT books with the word finance - and the horizons will open
for banks. Why is there little different software - they buy the same one from 2-3 manufacturers? Because fiddling with certification takes a long time, a lot, and as a result, it’s expensive, and if you miss it, there are no miracles, inside it’s still the same peacock ass (s) - errors in calculating interest, double write-offs, etc.
those. learn transactions and algorithms, and "fintech" will be added with a secure add-on, which, strictly speaking, cannot be mastered quickly))
