Recently left a company that specialized in developing platforms for online casinos (white label solutions for several operators). I was a tech lead there on the backend part for almost 3 years, and I will say right away - the work of a developer in this area is definitely underestimated from the outside. Many people think that a casino is beautifully drawn slots and marketing, but this is the tip of the iceberg. Under the hood is a full-fledged high-load distributed system that works with money 24/7. According to https://starofmysore.com/the-role-of-software-developers-in-online-casinos/, an online casino is essentially a banking system, only with gamification. You have accounts, balance, deposit/withdrawal, bonuses, transaction history, limits, KYC/AML rules and constant requests from regulators (Malta, Curacao, etc.). All this is written by developers, and not sent “from above”. We had to implement our own modules for document verification, data encryption, interaction with payments - from Stripe to obscure crypto-Gateway, and each gateway has its own cockroaches. The second topic is games. Even if the company uses external providers (Quickspin, Pragmatic, etc.), they need to be integrated. These are dozens of APIs, each with its own specifics, logic of bonuses, bets, RTP. The developer is responsible for ensuring that the session does not break at the right moment, the money does not "hang" in the transaction, and the result of the game does not raise doubts. This is especially important in live games, where bets are made in real time.
