3. Analytics & Performance

  • Implement analytics frameworks to measure:
    • User adoption
    • Application performance
    • System reliability
    • Mission outcomes

  • Support continuous improvement through metrics-driven optimization.

4. DevSecOps & Delivery Operations

  • Architect and maintain secure DevSecOps pipelines across development, test, staging, and production environments.
  • Implement CI/CD pipelines with automated:
    • Build processes
    • Unit and integration testing
    • Security scanning (SAST/DAST)
    • Container scanning
    • Infrastructure-as-Code validation
  • Support Authority to Operate (ATO)-aligned deployment processes.
  • Implement monitoring, logging, and alerting frameworks for operational awareness.
  • Ensure secure deployments within Government-assigned cloud environments and approved hosting platforms.
  • Enforce secure coding standards and compliance with DoD cybersecurity frameworks (e.g., RMF, NIST).
  • Support repeatable, rapid, and secure release cycles with rollback and resilience strategies.
Requirements:
