Required Technical Expertise * Oracle Specialist: Extensive experience with Oracle 19c/23c, specifically within Exadata environments. * Replication Expert: Proven track record designing GoldenGate (Classic and Microservices) for complex, high-volume data movement. * Infrastructure-as-Code: Experience designing automated deployment patterns for database infrastructure. * Design Pattern Fluency: Deep understanding of application design patterns and how they interact with the database layer. * Performance Guru: Expert-level knowledge of Oracle internals and Exadata-specific tuning.
