What I'm looking for

I'm seeking a remote Penetration Testing role in a high-performing security team.

At PwC, I execute black-box and gray-box penetration tests across web applications, APIs, and corporate infrastructure. For 10 clients, I uncovered 7 critical and high-severity vulnerabilities and validated complex issues including code injection leading to RCE.

Earlier, as an Information Security Analyst, I evaluated security controls across Linux and Windows environments and used custom GPT-based agents and Copilot to accelerate evidence and log analysis. At Ideale Group SRL, I designed IAM access matrices and improved order load times from 4 minutes to 20 seconds through SQL troubleshooting and Visual Basic application optimization.
