Do you have experience working with banking processing or banking processing systems?

Yes, I have experience working with banking processing. Specifically, I have participated in the development of systems that process transactions in real-time, ensuring security and compliance with PCI DSS requirements. Such systems need to handle high loads, be fault-tolerant, and protect data. For example, I have implemented integration with payment gateways, processing authorizations and clearing, as well as transaction monitoring for fraud detection.
