• Lead the design of modernization artifacts such as architecture blueprints, sequence diagrams, security models, and deployment workflows.
n
• Direct the implementation of DevSecOps pipelines, automated testing suites, and container orchestration (e.g., Kubernetes/OpenShift).
n
• Ensure technical alignment between development, security, data, and infrastructure teams.
n

n
• Apply DoDAF and enterprise architecture methodologies to guide system alignment with mission goals.
n
• Ensure all architectures meet DISA STIGs, NIST 800-53, RMF, and CPTC security mandates.
