Real-time payment fraud detection API — XGBoost (AUC-ROC 0.927) + FastAPI + Docker | Trained on IEEE-CIS dataset (590K transactions)
XGBoost fraud detection pipeline with advanced feature engineering for IEEE-CIS, focusing on cardholder UID, D‑column normalization, and group aggregations.
A production-ready fraud detection system using Random Forest & SMOTE. Handles severe class imbalance (3.5% fraud rate) and 80%+ missing data. Achieves 0.88 F1-score on IEEE-CIS dataset.
ML model to predict the probability of fraudulent online transactions — based on the IEEE-CIS Fraud Detection Kaggle competition using real-world e-commerce data from Vesta Corporation.
