Architecture Responsibility

Responsible for technology architecture and hands-on delivery direction across system design, deployment, DevOps, cost, scale, reliability, and production readiness.

Outcome

Transformed legacy infrastructure into a secure, cost-optimized platform, including AWS organizational consolidation.

Scale

Modernized a production platform over a multi-year growth period while improving cost, security, and operational consistency.

Architecture

  • Used ECS Fargate with Spot capacity to improve cost efficiency.
  • Standardized infrastructure management with Terraform.
  • Implemented G-Suite and AWS SSO integration for identity access.
  • Consolidated AWS organization structure to improve governance and operational control.

Lessons Learned

  • Cost optimization works best when it is designed into runtime architecture, capacity choices, and deployment automation from the start.
  • Terraform changes cloud operations from manual activity into governed, reviewable, repeatable engineering.
  • Identity, account structure, and access governance are core architecture concerns in any serious modernization program.
