The Business Challenge

  • Operational complexity — hybrid AWS, Azure, and Vultr environments with legacy manual configuration.
  • Pipeline fragmentation — outdated CI/CD (Bamboo) limiting velocity and standardization.
  • Scalability constraints — microservices spanning varying Kubernetes cluster types.
  • Security & access risk — over-privileged IAM, no centralized IdP integration.
  • Compliance hardening — PRISMA remediation across Commercial and GovCloud.

Strategic Implementation

CI/CD modernization — directed cross-functional migration from Bamboo to GitHub Actions and Azure DevOps, establishing standard pipeline practices across engineering teams.

Hybrid-cloud & container orchestration — architected production hybrid-cloud environments with Terraform, Terragrunt, and Bicep; orchestrated high-density Linux containers on EKS/AKS with Karpenter across EC2 and Fargate nodes.

DevSecOps governance & compliance — led PRISMA remediation with the DoD, audited complex AWS IAM, and integrated Google SAML with AWS IAM Identity Center.

Results & Impact

Accelerated Delivery

Migrated legacy environments to GitHub Actions, eliminating bottlenecks and unifying global pipeline standards.

Enhanced Security Compliance

Completed critical PRISMA remediation tasks for DoD compliance ahead of schedule.

Optimized Efficiency

Automation scripts and workflows saved hours of engineering time every sprint across DevOps teams.

Scalable Architecture

Flexible Kubernetes and hybrid-cloud topologies stabilized microservice availability for enterprise applications.
