  • I-9 verification and background check processing
  • Training and compliance integrations
  • Training, rostering, and coursework management
• Support integrations with internal legacy .NET applications
• Extend and enhance existing API patterns (e.g., Oracle Learning Origami) for future integrations

Collaboration & Delivery

• Collaborate with Oracle SMEs and DBAs to ensure data accuracy, performance, and compliance with Oracle standards
