What I'm looking for

I’m looking for a Security Analyst role where I can own SOC operations like cloud/EDR monitoring, SIEM/IDS triage, and detection rule tuning, while building security automation with Python and strengthening incident response and compliance outcomes.

I’m a Security Analyst with 2+ years of hands-on experience administering CrowdStrike Falcon, monitoring AWS security services (GuardDuty, CloudTrail, IAM Access Analyzer), and supporting SIEM and IDS/IPS alert triage and rule tuning across enterprise environments.

I focus on actionable security operations—conducting vulnerability assessments, tracking CVEs, and supporting incident response activities—while maintaining SOC 2–adjacent documentation and audit evidence. I use Python and Bash to automate security workflows, and I apply NIST CSF, OWASP Top 10, MITRE ATT&CK, and NIST SP 800-61r2 to guide detection logic, investigations, and compliance decisions, including responsible awareness of AI/LLM security risks.
