Security Analyst III @ Bolster AI

About

I hunt phishing campaigns, dismantle attacker infrastructure, and build automation that makes SOC teams faster — before threats reach end users. As a Security Analyst III, I specialize in cyber threat intelligence, email security, and brand abuse takedowns. My work sits at the intersection of adversary tracking, incident response, and detection engineering — analyzing domains, URLs, headers, IPs, and phishing kits to map campaigns and cut them off at the source. What I bring to the table: End-to-end phishing & scam investigation, from triage to takedown OSINT-driven adversary profiling and infrastructure analysis Domain, social media, ad, and hosted content takedowns at scale Python automation that reduces manual SOC workload and accelerates response Cross-functional collaboration with global providers across time zones Analyst mentorship and detection workflow improvement I'm currently exploring senior CTI, threat research, or security engineering roles where I can go deeper on intelligence operations and have real impact on attacker disruption. Open to connecting with threat intel teams, security researchers, and hiring managers in the cybersecurity space.
