Cloud Security Specialist at Kroll who raised client AWS compliance from 40% to 80%.

Brazil
Message

At Kroll, I assess and secure AWS environments for clients across multiple industries. I raised client compliance from approximately 40% to 80% through CSPM and Cloud Workload Protection programs.

I designed AWS landing zones and security foundations using Control Tower and Organizations. During a critical incident involving a compromised production EKS cluster, I traced attacker activity, confirmed there was no lateral movement, and coordinated rotation of exposed credentials.

I also automate cloud assessments with Python and Boto3, and support incident response across AWS and Kubernetes. I’m expanding into AI security, including LLM security, prompt hardening, and guardrails for generative AI.
