What I'm looking for

I’m seeking to tackle real-life challenges and leverage my technical expertise in network security to protect critical infrastructure and enhance the security posture of large enterprises.

At Quantex Technologies, I design, implement, and maintain enterprise network security infrastructure. I’m deploying remote-access VPN for workers to securely reach internal resources.

At Orange Business - Orange CyberDefense, I administered change requests across large-scale, multi-vendor environments using Fortinet FortiGate, Palo Alto Networks, and Check Point firewalls. I investigated severe incidents and provided RCA and RFO reports for resolved cases.

At Orange Business - Orange CyberDefense, I worked with Zscaler, Netskope, and Palo Alto Prisma Access solutions. I reported Zscaler SASE issues to engineering, verified two bugs and one enhancement, and provided Linux scripts to help investigate intermittent performance problems.

At Misr International University (MIU), I created course materials and taught topics including networking, cybersecurity, digital forensics, and Python programming. I also implemented machine-learning models for network traffic analysis and anomaly detection.
