I protect cloud, web, and network environments through incident response, DDoS mitigation, and security operations.
BrazilWhat I'm looking for
I'm protecting cloud, web, and network environments through hands-on security operations, incident analysis, and data protection work.
At Nexusguard, I analyze security events in real time and mitigate large-scale multi-vector DDoS attacks for customers across different countries. I investigate malicious traffic with Wireshark, Elasticsearch, monitoring platforms, and Looking Glass tools while supporting critical incidents within SLA requirements.
At Algar Telecom, I implemented and administered CASB, DLP, SWG, and CSPM solutions, created data protection policies, and assessed cloud environments for misconfigurations, malware, and compliance gaps. I also improved external security posture through analysis of internet-facing assets, SSL configurations, and application security headers.
My earlier work included firewall policy management, VPN and DNS troubleshooting, log analysis, WAF tuning, and perimeter incident response. I'm fluent in English and bring certifications spanning cloud security, AWS, Oracle Cloud Infrastructure, and ISC² cybersecurity.
