Rockstar🎓
Top SchoolHai To is a Senior Data Engineer with nine years of experience building real-time stream processing and scalable data pipelines across IoT, health-tech, and digital advertising. He has led data platform modernization and synchronization efforts at PlusDental and designed ETL and integration solutions at Bonial, while developing ML models and click-fraud detection early in his career. At Sensirion Connected Solutions (formerly AiSight) and now Roger, he focuses on production-grade stream processing, infrastructure as code, and Kubernetes-based deployments.
