Open-source real-time card-transaction fraud detection system. Trains a LightGBM model on the IEEE-CIS dataset, exports it to ONNX for language-agnostic inference, and serves scoring with SHAP-based explainability through a microservice architecture: gateway, inference, feature store, decision policy, and Kafka-backed audit trail. Grew out of MIT research benchmarking SHAP explainability configurations for low-latency fraud scoring.
