About Rafik

Network & Security Engineer with 9 years of experience, I support companies in the design, deployment, and optimization of their network and security infrastructures.

During my assignments, I have worked in complex and demanding environments (large groups and international contexts), where I have developed solid expertise in equipment integration, network traffic management, architecture security, and operational maintenance.

I am involved in the entire infrastructure lifecycle:

🔧 Deployment and integration of network & security solutions
🔍 Traffic analysis and filtering rule implementation
🛠️ Incident management and advanced technical support
📈 Performance optimization and monitoring
🔄 Infrastructure evolution and modernization projects

Accustomed to working with various technologies (Cisco, Fortigate, Palo Alto, Aruba, Checkpoint, F5…), I quickly adapt to client environments and business challenges.

Rigorous, autonomous, and results-oriented, I make it a point of honor to provide reliable, secure solutions tailored to the specific needs of each project.
