About Metin

Hello,

Is your company safe from a cyberattack or data breach?

Cybersecurity Engineer with 3 years of experience at Health Insurance (CNAM), I am accustomed to protecting critical and sensitive data. I now bring this rigor to your security.

My areas of intervention:
🛡️ Pentest & Offensive Audit (Web & Network): I simulate attacks (Ethical Hacker) to identify your vulnerabilities before the hackers do (eJPT Certified).
⚙️ DevSecOps: I integrate security directly into your development projects for robust code from the start (DSOF Certified).
🏥 Compliance & Health: Technical support for sensitive environments.

Why work with me?

Pragmatic approach: I don't just give you a report, I help you fix it.

Institutional rigor combined with freelance agility.

Let's discuss your needs during an initial conversation!
