Things I built and labs I've worked through — documented on GitHub.

Enterprise Campus Network

Enterprise Campus Network

Designed and implemented an Enterprise Campus Network with an HQ, multiple campus networks, and a dedicated DMZ zone.Configured VLANs, Inter-VLAN Routing, DHCP, EIGRP (AS 10), VRRP, STP, Port Security, NAT/PAT, and Layer 2/Layer 3 redundancy.

Implemented VRRP gateway redundancy and STP-based Layer 2 redundancy to improve network availability and resilience. Configured DHCP services, 8-hour IP lease time, dynamic routing, and secure access controls across the campus network.

Simulated public-facing services in the DMZ and performed end-to-end connectivity testing across internal and external network segments.

Multi-office Enterprise Network

Multi-Office Enterprise Network

Designed and implemented a simulated Multi-Office Enterprise Network using EVE-NG, connecting two office networks through an edge router. Configured VLANs, trunking, DHCP, Inter-VLAN Routing, OSPF dynamic routing, and a static default route.

Simulated an external ISP network and used OSPF default-information originate to provide external connectivity. Verified end-to-end communication across VLANs, offices, and the external network.
