Open source software engineer at Red Hat, leading Debezium (a change data capturing platform based on Apache Kafka) and Hibernate Validator (declarative validation of your Java beans). I'm the spec lead of Bean Validation 2.0 (JSR 380).

I also founded the MapStruct project, a compile-time code generator for bean-to-bean mappings, and ModiTect, tooling to simplify the work with Java 9 modules and their descriptors.
