Summary

Senior🎓
Top SchoolAlexander Gude is a Senior Staff Machine Learning Engineer with 12 years of experience building and operationalizing fraud, risk, and security ML systems at scale for consumer finance. He has led cross-functional, customer-facing programs that combined modeling, rules, and alerts to cut fraud volumes by an order of magnitude while enabling product growth—e.g., driving instant bank account onboarding that increased paycheck deposits 90%. A former CERN particle physicist, he brings rigorous experimental thinking to production ML, having migrated large model fleets to cloud CI/CD pipelines and saved millions in operating costs. He excels at translating high-recall monitoring into targeted models and rules, briefed regulators on anti-fraud practices, and built the first in-product real-time account-takeover model at Intuit. Outside of work he’s a cyclist and occasional photographer, applying the same data-driven curiosity to projects ranging from geospatial photo recommendation engines to large-scale image embedding research.
