## About

```text
At Mercado Libre SRL, I supported Key Account Managers with large seller accounts, resolving shipping and cost issues, platform-related claims, reputation problems, and improper suspensions. I also coordinated escalations with internal teams and reviewed confidential account information and KYC documentation.

I redesigned team workflows, reducing operational errors by 2.5 percentage points and repeat claims by 4%. I used SQL in BigQuery and Excel to identify patterns and root causes, and Claude and ChatGPT to streamline analysis and processes.
