Advice for backend developers in fintech, especially for Robo-advisory heavily reliant on third parties: Use Hexagonal Architecture.
The idea is to decouple the Core Domain from external services.
Think of your Domain as a wall socket and the Broker as a charger. It works with any charger if you have the right Adapter.
If you switch from Derayah to Alpaca, you just swap the Adapter without touching the Domain logic.
"Focus on building a clean Domain, and treat everything external as a plug."
