Projects

This page showcases some of the hands-on networking and IT projects I’ve completed while working on my certifications and technical skills. From configuring Active Directory in a Windows Server environment to designing Cisco networks in Packet Tracer and multi-vendor networks in GNS3, these projects demonstrate practical experience in networking, infrastructure, and troubleshooting.

Cisco Packet Tracer

Routing and VoiP

This project is a simulated enterprise network that demonstrates real-world concepts across routing, switching, and voice technologies. The design follows a hierarchical model with a multilayer core switch, access layer switches, and edge routers, using OSPF for internal routing and BGP to simulate external connectivity. VLAN segmentation separates data and voice traffic, with DHCP providing automated IP addressing, while VoIP is implemented using Cisco Call Manager Express for phone communication. QoS is applied to prioritize voice traffic, highlighting my ability to design and configure a multi-layer enterprise network.

GNS3

Learning GNS3

This is my first GNS3 project, and right now I’m focused on building the full environment before diving into the configurations. I set up a multi‑vendor topology using Juniper routers and switches, and a FortiGate firewall, all connected in a clean, layered design. Even at this early stage, this lab is helping me get comfortable with real‑world device images, interface mapping, and how different platforms link together inside a virtual network. It’s the foundation I’ll use to practice routing, switching, and firewall policies as I continue growing my skills.

Cisco Packet Tracer

LACP EtherChannel

This lab shows how I built a redundant switching environment using LACP EtherChannel on both Layer 2 and Layer 3 links. I configured trunked Port‑Channels between the access and distribution switches, created a routed Port‑Channel between the distribution switches, set up inter‑VLAN routing, and verified full connectivity to the server. I also adjusted the EtherChannel load‑balancing method to use source‑and‑destination IP for more efficient traffic distribution.

Cisco Packet Tracer

DHCP

This lab focuses on setting up DHCP in a small routed network. I practiced creating multiple DHCP pools on a router, configuring excluded addresses, and using a second router as both a DHCP client and a DHCP relay. The goal of this project is to understand how DHCP works across different subnets and how routers pass client requests when the DHCP server isn’t on the same network. It’s a foundational lab that helps me build confidence with real‑world IP addressing and host provisioning.

Cisco Packet Tracer

OSPF

This lab helped me practice building a multi‑router OSPF network and verifying end‑to‑end connectivity across several subnets. I configured OSPF on each router, checked that all routes were being learned correctly, and confirmed that hosts could reach the internet through the full path. This project strengthened my understanding of dynamic routing, next‑hop relationships, and how to read and troubleshoot routing tables in a real topology.

Cisco Packet Tracer

Mega Lab

For my final CCNA lab, I configured a multi‑site enterprise network connecting an HQ location, two branch offices, and an external corporate edge. I configured OSPF across all routers, set up ROAS for inter‑VLAN routing, built EtherChannel bundles with both PagP and LACP, and deployed RPVST throughout the switching environment. I enforced port security and BPDU Guard, and implemented both static NAT and PAT based on each site’s needs. I also created a centralized DHCP setup and applied multiple ACLs to shape and protect traffic across the network. The result was a fully functioning multi‑site environment that showcased my ability to build, secure, and troubleshoot complex networks while keeping everything organized and intentional.

VirtualBox

Windows Server + Client

I built a Windows Server domain environment and practiced the core skills used in real IT support roles. I installed and configured Active Directory, created organizational units, added users and computers, and joined a Windows client to the domain. I also worked through common helpdesk tasks like resetting passwords, unlocking accounts, and verifying group membership. This project strengthened my understanding of identity management, domain services, and how Windows clients authenticate and receive policies in an enterprise environment.
