Request: Prime bank (NDA) inquired about a module that would allow fraud prevention officers to detect fraud cases and block fraudulent transactions. 

Solution: In response, we designed an internal webpage that receives event data via an API. This data is then analyzed using an ad hoc algorithm. When a potential fraud case is identified, an officer could press the button that blocks the transaction by calling other APIs.

Result: The solution was developed and integrated within two weeks and has saved the bank between $50,000 and $75,000 each month
