## What I'm looking for

I’m looking to grow into SOC and Blue Team work, focusing on security monitoring, alert triage, and incident response.

## About

```text
At Telefônica Vivo, I studied malware behavior in sandboxes and assessed endpoint defenses, documenting evidence and results. I also mapped defensive capabilities and helped create documentation connecting attack and defense teams.

In Telefônica Vivo’s Offsec Ops Team, I supported pentest planning by checking scope and prerequisites, tracking remediation, and verifying retests. I’m now focused on SOC and Blue Team work, building on academic experience with Wazuh monitoring, alert triage, and initial incident response.
