As a member of the anti-fraud team, I developed ACH transfer fraud defenses in Python. I worked closely with a data science group to launch real-time machine learning inference pipelines to identify fraudsters and implemented targeted account restrictions to protect the firm from fraud loss while enabling a positive user experience.
• Implemented new fraud evaluation flows, generating a total of $1 million in monthly fraud savings
• Created 100 real-time and offline machine learning features for 20M users
• Worked with two engineers to ship a cash advance product, resulting in a 10% increase in early access funds with no change in fraud loss
