Hi, my name is
Igirimbabazi Kayumba Regis
Computer Engineering Student
Network Administration & Security Infrastructure
I specialize in designing resilient enterprise network topologies, configuring firewalls, and orchestrating secure IT infrastructure. Currently studying Computer Engineering at Vistula University, Warsaw.
About
I am Regis, a computer engineering student with a deep interest in enterprise systems, network topologies, and security engineering.
My journey in technology centers on understanding how network nodes communicate, how systems can be hardened against intrusions, and how complex routing protocols scale. My academic foundation at Vistula University complements practical operational experience in IT support systems, logistics coordination, and customer-facing troubleshooting.
I focus on designing secure, redundant network architectures (including Cisco IOS configurations, VLAN segmentation, and perimeter firewall security rules). I aim to bridge rigorous technical implementations with seamless system administration.
