Cybersecurity Analyst with hands-on experience in risk assessment, threat modeling, vulnerability analysis, and digital forensics. Has completed NIST RMF-based assessments, STRIDE modeling, Nmap scanning, and forensic investigations using tools such as Lynis, Mobsf, Autopsy, FTK Imager, and Nmap.

Cybersecurity Analyst at Cyberguard lounge (2025-08 – 2025-11)

• Led end‐to‐end risk assessments (NIST RMF), executing 100+ security checks across infrastructure and applications to identify and prioritize risks.
• Performed STRIDE threat modeling, mapping and documenting 30+ attack vectors and associated threat scenarios.
• Conducted Lynis audits and MobSF application reviews, combining automated and manual testing to surface issues and validate controls.
• Identified and triaged 10 critical vulnerabilities, driving remediation plans and verification testing.
• Delivered measurable risk reduction and reporting, achieving a 40% decrease in unidentified risk and producing risk registers, POAMs, and executive/technical briefings.

Cybersecurity Intern at Centre for cybersecurity studies & research (2024-09 – 2024-11)

• Conducted reconnaissance and host discovery using Nmap and Zenmap to scan remote subnets, identify live hosts, and enumerate IP ranges.
• Performed service and port enumeration with Nmap scripts and Netcat to detect open ports, running services, and software versions.
• Validated findings through manual probing with Netcat for banner grabs and targeted checks, confirming services and reducing false positives.
• Created network maps and visualizations with Zenmap, documenting topology, asset roles, and exposure points for the security team.
• Supported vulnerability discovery by correlating scan outputs with CVE research, prioritizing issues, and producing analyst-ready summaries.
