What I'm looking for

I am seeking a SOC/threat-focused role where I can apply SIEM and threat-intel skills, reduce false positives, mentor analysts, and grow into senior incident response responsibilities.

I am a cybersecurity professional with 4.8 years of hands-on experience in Security Operations Center (SOC) analysis, threat investigation, and incident response across government and enterprise environments.

I have implemented and managed SIEM deployments (ELK, IBM QRadar), integrated 300+ endpoints, and tuned detection rules to reduce false positives by up to 30% while maintaining 95% SLA compliance for incident response.

My work includes threat intelligence integration (MISP, VirusTotal, Anomali), IOC-based detections, phishing and malware analysis, and delivering intelligence reports and SOPs adopted by client SOCs.

I have trained SOC analysts, managed 24x7 shift rotations, and received consecutive client appreciation awards for investigation excellence and effective incident resolution.
