Top SchoolStuart Douglas is a Staff Engineer with 16 years of experience building high-performance Java middleware and cloud-native systems, now based in Orange, NSW and working at Block after a long tenure at Red Hat. He has deep back-end expertise across projects like Quarkus, WildFly, Undertow and Hibernate, with notable contributions enabling native image support, HTTP/2 features, and performance-focused refactors. Stuart combines systems-level thinking with pragmatic DevOps skills—authoring shutdown and deployment tooling for WildFly Core and improving build and native-image pipelines for JBang and Quarkus. He’s an active contributor to widely used open-source stacks, often tackling tricky areas like classloading, security (Elytron), and low-level I/O (XNIO). Colleagues rely on him to simplify complex lifecycle and integration problems while reducing resource use through lazy instantiation and allocation optimizations. Trained in computer science at the University of Wollongong, he pairs academic foundations with a long track record of production-hardened improvements to major Java platforms.
