What I'm looking for

I’m looking for a hands-on cybersecurity role where I can monitor threats in SIEM tools, engineer detections, investigate incidents end-to-end, and strengthen security posture with compliance-minded risk management and clear documentation.

I’m a cybersecurity analyst with hands-on experience in threat monitoring, incident response, vulnerability assessment, and SIEM engineering across cloud and hybrid environments. I’m proficient in Microsoft Sentinel, Splunk, and Azure security tools, grounded in NIST 800-53, HIPAA, PCI-DSS, and GDPR compliance frameworks.

I investigated 15+ security incidents, achieving a 30% reduction in response time, and engineered 20+ automated detection rules that improved threat coverage by 50%. In my Security Analyst (Junior) role at Block (Cash App), I monitored 5M+ daily transactions, reduced MTTD by 35% using PCI-DSS-aligned detection rules, drove remediation of 20+ critical findings (90% of high-severity issues within SLA), and supported PCI-DSS audit readiness through rigorous evidence and access-log reviews.
