I enjoy collaborating with cross-functional teams and can leverage my technical expertise to drive success. My goal is to contribute to an organization that values innovation, fosters growth, and promotes a secure and resilient IT infrastructure.In Security Operations, I’ve handled over 300 simulated alerts across a wide range of threat scenarios, including phishing, malware, abnormal process activity, and command-and-control (C2) beaconing. I’ve analyzed SIEM data using tools like Splunk, Azure Sentinel, and QRadar, and used EDR, CTI, and PowerShell to take appropriate mitigation actions—from isolating hosts to blocking malicious IPs. I also led a cloud security project where I built an Azure Sentinel dashboard to visualize brute-force attacks by geolocation.I’m passionate about building secure, scalable, and compliant environments—whether through better security controls, well-designed infrastructure, or clear and actionable policy. I’m always looking to grow, contribute, and connect with others in the cybersecurity space.
