What I'm looking for

I’m looking to drive security operations end-to-end—SIEM monitoring, incident response, and risk assessments—while continuously improving detection and reducing MTTR/false positives through automation, correlation, and cross-team collaboration.

I’m a cybersecurity engineer with a strong track record across NOC/SOC environments and network engineering. I focus on managing security incidents, reducing vendor/third-party risk, and optimizing the availability of critical services.

I specialize in incident response and forensic investigations, using NIST 800-61 to reduce MTTR/MTTD for DDoS, malware, and breaches. I administer and harden security platforms, including SIEM monitoring plus IDS/IPS, WAF, EDR, antivirus, and FIM.

I also collaborate closely with networking teams to improve resilient architectures. My experience includes configuring BGP, OSPF, EIGRP, VLANs, NAT/PAT, and high availability patterns like HA/HSRP—while also tuning policies to reduce false positives and strengthen confidentiality and integrity.

I bring a continuous-improvement mindset, leading risk assessments for third parties and cloud providers and shortening remediation cycles. I aim to deliver measurable security outcomes through automation, correlation scripts, and clear security recommendations that drive adoption across technical stakeholders.
