Jeff Mesnil is a seasoned software engineer with 19 years' experience building robust, open-source server-side systems, currently at IBM after a long tenure as a senior principal engineer at Red Hat. He specializes in Java application servers and messaging (WildFly, JBoss EAP, ActiveMQ Artemis, HornetQ), with a track record of pragmatic contributions that improve JVM/runtime configuration, JMS bridging, and legacy client support. A committed open-source advocate, all his professional and personal code is public—much of it hosted on GitHub—and he thrives in collaborative, transparent development environments. He combines deep backend expertise with occasional mobile and iOS work (notably an MQTT Objective-C client) and has authored technical material for O’Reilly. Based in Grenoble, France, he brings engineering rigor informed by sustainability and humane values, and pursues photography as an amateur creative outlet.
