Sounds very impressive. It'll definitely scale if they can somehow build it with 3 coders.
I would have thought you could start with a bog standard CRUD setup. How many customers are they serving at the moment? How many queries is one customer going to make each day?
What part of a bank are they actually trying to make? Just current accounts? Or multi asset market making? The requirements are quite different.
Also, on the business side, why does the UK market need another bank? It's a totally commodity service. Why would I want to use this bank? Do they offer something better?
