I have hands-on experience with physical Cisco networking equipment and practical enterprise network projects involving OSPF, EIGRP, VLANs, HSRP, VPNs, Cisco ASA Firewalls, and AAA authentication.

My technical background also includes Windows Server, Active Directory, VMware ESXi, Cisco CME, FreePBX, and Python-based network automation using GNS3.

I'm currently studying Networks and Cloud Computing at the National University of Sadat City, continuously developing my technical knowledge through practical labs and networking projects.

I'm passionate about designing, securing, and troubleshooting reliable network infrastructures, and I'm always looking for opportunities to learn, collaborate, and grow professionally.
