About Gad

Web developer and cybersecurity enthusiast, I help companies create high-performing websites while ensuring their security.

Thanks to my dual profile, I don't just design modern and fast applications: I also make sure they withstand attacks. My goal is simple — deliver reliable, secure, and production-ready solutions.

💻 Web Development:

Creation of modern and optimized websites
Redesign of existing sites
Rapid development with powerful tools
Deployment and support

🔐 Cybersecurity (Pentest):

Real-world penetration testing
Analysis and remediation of vulnerabilities (OWASP Top 10)
Attacker-oriented approach (CTF, offensive practice)

Combine performance + security + simplicity.
A beautiful, fast site… but above all, one that's hard to break.

I work with seriousness, transparency, and efficiency, with a results-oriented logic.
