What I'm looking for

I seek roles where I can apply CTI, OT/ICS and cloud security skills to protect critical infrastructure, influence strategy, develop tooling, and brief leadership in a collaborative, security-focused organization.

I am a Cyber Threat Intelligence and Security Analyst with hands-on experience tracking threat actors, analyzing malware and mapping campaigns using OpenCTI and AlienVault OTX.

I combine OSINT and vHUMINT tradecraft, OPSEC and adversary behavior analysis to produce decision-ready intelligence for technical and non-technical stakeholders.

In OT/ICS I have performed system audits, asset validation, access control reviews and incident root cause analysis for PLC, DCS and SCADA systems at refinery environments while applying cybersecurity principles to safety-critical engineering workstations.

I have developed Python-based security tools, analyzed network traffic for intrusion detection, authored executive-level intelligence reports, and briefed senior leadership on risks, trends and impacts.
