Hi, I'm

Agustina Fassina

DevOps · Cloud Infrastructure & Automation

I design and run cloud platforms: deployments, account security with daily scans and metrics, automation, and FinOps habits like Cost Explorer by project tag so spend stays predictable in production. I also build product backends in .NET when an API is needed, create and maintain Azure DevOps pipelines, and as a hobby I like building things with code, like dashboards and games.

The keys that never rotated

Ninety-day rotation was written in the policy. The oldest access key in the account was 412 days old. What we measured, what we automated, and why rotation alone is not security.

Postmortem

The security group rule that outlived the ticket

A temporary PostgreSQL port opened for debugging stayed in production for six weeks after the ticket closed. The database was never breached, which almost made it worse.
