• Build observability capabilities that surface pipeline failures, data drift, and quality issues before they affect downstream models or fraud rules.
• Partner with Data Scientists and Fraud Ops to translate fraud-prevention use cases into scalable, resilient data products while maintaining consistency between batch and real-time processing.
