He combines solid Core Java expertise (Oracle Certified) with practical DevOps skills—Docker, Kubernetes, Helm—and cloud experience on AWS and Azure, having earned an AWS Developer certification. His open-source contributions to WSO2’s Identity Server and related projects demonstrate hands-on work in identity, OAuth, JWTs and SCIM, including bug fixes, cache and session fixes, and automation of test coverage. At IFS he worked on server frameworks using Quarkus and OpenLiberty, showing comfort with modern Java runtimes and production-grade distributed systems.
