Pubudu Gunatilaka is a Director of Engineering with 12 years of experience leading API management and cloud-native architecture at WSO2, where he currently directs product architecture for the API Manager. He combines hands-on backend engineering—contributions to WSO2’s CEP/Siddhi engine and throttle integration—with strategic leadership in Kubernetes-native gateways, Istio integration, and Choreo Connect. A frequent speaker at APIDays, Nordic APIs and other conferences, he shapes industry thinking on API security and scalable enterprise API strategies. His technical depth spans transport and event-conversion work (TCP/Binary converters for Siddhi) as well as documentation and UX refinements, reflecting a rare mix of core systems engineering and product polish. Based in Sri Lanka, he has driven WSO2 middleware decisions from early PaaS work through modern cloud-native deployments. Colleagues rely on him for pragmatic designs that translate complex CEP and API concerns into production-ready, high-performance solutions.
