Nodejs banking project

Hello guys
I just learned nodejs fundamentals so I’m trying to create a real-life banking system with nodejs
So basically I saw lot of tutorials of banking system but not for nodejs but rather for Python which I only have the fundamental knowledge in nodejs

So I need help if someone could put me through the module to read their documentations for the banking project be successful

And lastly can I use a fintech like stripe, flutterwave, paystack etc to integrate a transfer within bank to bank or does banks uses api for transfer within bank to bank or wallet to wallet
