What is your experience or attitude towards development in the banking systems sphere?

In the field of banking systems, it is important to pay special attention to security, reliability, and compliance with regulatory requirements. My experience includes testing functionalities related to transactions, user authorization, and error handling. I am also familiar with test automation for banking APIs, where it is critical to verify data processing accuracy and resilience under load. It is important to thoroughly test boundary scenarios and potential errors to avoid financial losses and failures.
