What I'm looking for
I am a dedicated cybersecurity professional with two years of hands-on experience across SOC and security engineering roles. I focus on threat detection, incident response and continuous improvement to protect organizational assets.
I have deployed and optimized SIEM solutions (ArcSight, Rapid7, QRadar), increasing threat detection coverage by 35% and integrated 10+ log sources to improve event correlation. I engineered detection use cases and custom parsers that reduced false positives by 40%.
In SOC roles I monitored real-time alerts and logs, which helped reduce incident response time by 30% and accelerated low-complexity incident resolution by 25% through evidence collection, initial assessments and timely escalation. I conducted regular QA and SIEM/logger health checks to ensure 99% system uptime and reliable alerting.
I hold industry certifications and completed postgraduate cybersecurity coursework, and I bring strong communication, customer-service orientation and task management skills. I am collaborative, eager to drive detection engineering improvements, and committed to continuous learning and professional growth.
