Summary
Fabien Dumay is a seasoned senior consultant and systems engineer with over three decades in IT, combining deep legacy AS/400/iSeries expertise with modern Linux, middleware and Java-based infrastructure. He has led design and development of monitoring and automation platforms (notably IP400) and rebuilt critical applications while running and securing his own multi-service server stack (GitLab, Artifactory, Redmine, mail, mirrors). Comfortable across WebLogic, WebSphere, Sonic MQ/ESB and Java 5–8, he bridges operations and development—writing Java and shell automation to harden deployments and speed incident resolution. Known for being curious, security-minded and quality-driven, he regularly takes on hands-on system integration, 2nd/3rd line support and service migrations for enterprise customers. Based in Zoetermeer, he blends pragmatic realism with a willingness to go the extra mile to deliver reliable, auditable solutions.
