• Implement ServiceNow REST integration for white-glove routing intake path
• Build and maintain storefront backend services (API layer between frontend UI and platform components)
• Implement DataCard write-back path in coordination with Solution Architect
• Design and maintain async job queue management and retry logic across all integration surfaces
• Structure output metadata for DataCard provenance records per DoD distribution statement requirements
