Über mich
I'm a security engineer with 5+ years of experience in application security, specializing in automated code auditing and vulnerability detection.
I built my own multi-language security scanner that combines CodeQL, AST taint tracking, and Semgrep to detect OWASP Top 10 vulnerabilities including SQL Injection, XSS, Path Traversal, and Command Injection.
