What I'm looking for

I’m looking for a security team where I can lead incident response and security operations, strengthen detection and monitoring, and responsibly apply AI to improve threat hunting, SOC workflows, and governance aligned to NIST and ISO 27001.

I’m a results-driven cybersecurity specialist with over 5 years of progressive experience in information and cyber security, now focused on incident response and security operations. My work bridges technical security practice with responsible AI adoption, integrating AI tooling into core security functions like AI-assisted threat hunting and automated SOC workflow design.

I’ve implemented and improved security monitoring and detection capabilities across SIEM, EDR, and firewalls—building custom detection rules, authoring NIST-aligned incident response policies and playbooks, and driving measurable improvements in incident response performance. I also operationalize proactive threat intelligence by aggregating open-source feeds and internal telemetry, using AI-assisted extraction to surface high-signal indicators and reduce false positives.

Across my roles, I emphasize risk management, compliance, and actionable governance—supporting ISO 27001 ISMS work, maintaining alignment to NIST and security controls, and enforcing data protection expectations. Most recently, I engineered AI-assisted threat hunting workflows and established monitoring for AI platform usage to improve visibility and strengthen controls in enterprise environments.
