AWS platform consolidation + security hardening

Sanitized case study: consolidated a multi-cloud product platform onto AWS-only, improved auth and edge protections, and migrated the data layer to simplify operations.

What changed

  • Consolidated GCP Cloud Run + AWS services into an AWS-only runtime and deployment baseline.
  • Updated authentication flows and deployment configuration to support the new platform model.
  • Added CDN + WAF protections to harden the edge and improve performance.
  • Migrated MongoDB Atlas to Amazon DocumentDB with cutover planning and production validation.

Why this is high leverage

  • Lower operational surface area (one cloud, one primary runtime, one set of controls).
  • Better security posture at the edge (WAF policies + safer defaults).
  • Simplified data operations with AWS-native compatibility and clearer runbooks.
