## About

```text
At Serasa Experian, I work in Information Security across IAM, IGA, PAM, and process automation. I manage identity and access lifecycle activities, including provisioning, reviews, changes, and revocations.

I use SailPoint, Okta, CyberArk, and Centrify/Delinea across access management environments. I also support the Assurance team in structuring RBAC profiles and permissions.

I developed automation to analyze exposed credentials identified by Axur, using PowerShell and LDAP/Active Directory for validation. I evolved this work to check exposed credentials from external environments against valid credentials in clients’ Mainframe environments.

I also automate processes with Python, SQL, Power Automate, and REST APIs, integrating tools such as ServiceNow, Okta, CyberArk, and Axur. My work includes access governance, audits, operational indicators, incident and request handling, and continuous process improvement.
