About

I’m a cybersecurity engineer with hands-on experience across cloud security, SIEM operations, incident response, and threat simulation. My background includes working in both academic and enterprise settings to implement security tools, build detection pipelines, and conduct red team simulations. At SUNY-FMCC, I currently manage a cloud-based cyber range built on AWS, where I lead training sessions using MITRE ATT&CK techniques, Splunk dashboards, and QRadar rule tuning. I’ve delivered incident response and threat-hunting exercises to over 80 students in real-time attack environments. During my cybersecurity internship with a red team project partnered with the NSA, I focused on OWASP Top 10 testing, cloud vulnerability analysis, and AWS Security Hub automation. I also bring previous experience in compliance-driven environments, working on PCI DSS and ISO 27001 audits, firewall and VPN configuration, and vulnerability remediation using tools like Nessus and IBM AppScan. I’m passionate about threat detection, cloud infrastructure defense, and building scalable security operations.
