This post details Mapfre Insurance's modernization of fraud claims processing by integrating graph-based features with ML models on AWS. It introduces a technical architecture built on Amazon EMR Serverless, Apache Iceberg, AWS Glue Data Catalog, and AWS Lake Formation. The solution utilizes Neo4j for graph enrichment and Apache Airflow on Amazon MWAA for orchestration. A key contribution is the resilient integration with Guidewire Claims via AWS Lambda, including retry mechanisms, dead-letter queues, and secrets management using AWS Secrets Manager for real-time fraud alert actionability.
