What I'm looking for

I seek roles in Linux system administration or security development operations where I can build automation, improve incident response, and work with cross-functional teams to harden production environments.

I am a security-focused support engineer specializing in Linux systems administration, security automation, and threat intelligence. I build automated tools and pipelines—like ransomware leak monitoring integrated with Ransomlook and a CVE tracking/alerting pipeline across Feedly, Ransomlook, and Salesforce—that reduced manual review time by 90% and enabled proactive vulnerability management.

I deliver 24/7 technical support across LATAM Fortune 500 clients, handle incident triage and Linux-based security infrastructure, and work with director-level stakeholders on vulnerability assessments and incident response. I have hands-on experience with Trellix Database Security, Waratek RASP, virtual patching, and monitoring rule tuning for secure Java deployments.
