Top SchoolEmmanuel Bernard is a veteran open-source architect and founder with over 21 years of experience, known as a Java Champion and co-founder/lead of Quarkus and multiple Hibernate projects. He blends hands-on engineering—contributing core features to Hibernate ORM, OGM and Validator—with strategic leadership as Red Hat’s Chief Architect for Application Services and Middleware, where he shifted teams from product to SRE mindsets to build managed cloud services like a Managed Kafka offering. A prolific speaker, podcaster (Les Cast Codeurs) and standards contributor, he brings rare depth in Java persistence, full-text search and cloud-native Java. Now founding Hexactgon, he’s applying that platform and open-source expertise to agentic AI and advising transformations, pairing technical rigor with product and platform thinking. An understated strength is his ability to translate company strategy into concrete technical direction while fostering cross-team architect communities.
