Built real-time fraud detection features with Apache Flink (velocity features per email/device). Led the graph database POC (Neo4j) for fraud detection, later extended with IBAN integration. Enabled the risk scoring model and introduced provider fraud labelling for refinancing. Applied engineering best practices to Python CI/CD pipelines. Managed Kafka infrastructure via Terraform (topic creation, permissions, DLT retention). Attended Flink Forward 2024 and brought learnings back to the team.
