About Christian

Freelancer in cybersecurity, I offer web application pentesting services, defensive security auditing, and modern web development.

Certified Google Cybersecurity and TryHackMe SAL1, I rely on a real infrastructure: a VPS with Wazuh SIEM on which I practice daily. I have completed numerous offensive and defensive labs on TryHackMe and CyberDefenders, and I actively conduct penetration tests on my own infrastructure (phantomsecurity.tech).

What I can do for you:
- Web application pentesting (OWASP Top 10, recon, CVSS reporting)
- Defensive security auditing (service exposure, SIEM, WAF)
- Modern website development (React, Vite, HTML/CSS)
- Professional security report with concrete recommendations

Tools: Nmap, Burp Suite, Gobuster, Nikto, Wazuh, Wireshark, Python.
