At HacFy, I performed vulnerability assessments and penetration testing across web applications and REST APIs. I identified, validated, and documented 13 critical and medium-severity vulnerabilities, with evidence, reproduction steps, risk context, and remediation guidance.

I incorporated AI-assisted reconnaissance and payload generation into testing, then manually checked results against real behavior to avoid false positives. I also researched relevant CVEs and security advisories and evaluated security tools through proof-of-concept testing.

I built the AI Cyber Defense System, a real-time monitoring dashboard using FastAPI and React for security event analysis and alert streaming. It includes MITRE ATT&CK mappings, ISO 27001-aligned detection rules, and incident investigation workflows.
