Scope
Enterprise network simplification addressed both cloud cost and the operational drag of fragmented patterns repeated across many VPCs.
What changed
- Led consolidation of NAT Gateway usage to reduce recurring cloud spend.
- Orchestrated an enterprise DNS migration to address security findings across global networks.
- Migrated AWS ACM certificates from email validation to automated DNS validation, removing manual approval from supported renewal paths.
Outcome
The work simplified recurring network operations and reduced cost and security exposure. It is earlier platform work, separate from the current AI-era SDLC chapter.
