What I'm looking for

I seek a hands-on SOC or incident response role where I can reduce dwell time, automate playbooks, improve cloud defenses, and translate technical risk for stakeholders.

I am a SOC analyst with over five years of experience in incident response, threat detection, and cloud security across enterprise and hybrid environments. I have led 300+ incident investigations, automated containment with SOAR and EDR integrations, and optimized SIEM rules to reduce false positives and improve visibility.

I focus on measurable impact—cutting response time, preventing business disruption, and improving user awareness through phishing programs. I author SOPs and executive-facing reports, bridge technical findings to business risk, and apply frameworks like MITRE ATT&CK and the Cyber Kill Chain to harden environments.
