Administer, configure, and troubleshoot Siebel Gateway, Siebel Enterprise Server, Siebel Web Server Extension (SWSE), and related infrastructure components.

Execute code promotions, repository merges, migrations, and release management activities across all environments.

Troubleshoot complex Siebel performance issues, server bottlenecks, component failures, enterprise synchronization issues, and application outages.

Monitor application health, analyze server logs, execute capacity planning, and establish proactive system maintenance routines.

Support integrations between Siebel CRM and external systems using Siebel EAI, Integration Objects, Web Services, RESTful APIs, and XML payloads.

Collaborate with Database Administrators to perform Oracle database performance monitoring, SQL troubleshooting, and query optimization.

Maintain Siebel repository configurations, workflows, Business Services, Business Components, Applets, Views, and Open UI customizations.

Manage user access control, user profiles, system backups, disaster recovery procedures, and day-to-day computer operations.

Author comprehensive operational procedures, technical documentation, architecture diagrams, and support runbooks following ITIL-based service management standards.

Qualifications
