How would you design a banking system.
Clarify the customers, account and transaction operations, consistency guarantees, security requirements, and regulatory constraints before proposing an architecture. Explain how an ML-assisted fraud or risk decisioning path would integrate with the transactional core, including offline training, online inference, evaluation, monitoring, and failure handling. Address data protection, auditability, availability, disaster recovery, and degraded-mode behavior.
