What I've Built

Hands-on implementations that go beyond theory into real-world network architecture.

University Project

Cisco SD-WAN Full Implementation

Designed and deployed a complete Cisco SD-WAN fabric from scratch as part of my university capstone project — simulating a real enterprise multi-site deployment.

  • Built full controller infrastructure — vManage, vSmart, vBond — and integrated edge devices into an existing enterprise network
  • Configured QoS, security, and application-aware routing policies across the SD-WAN overlay to ensure optimal traffic handling per-site
  • Established IPsec tunnels with BFD monitoring between all sites for encrypted, resilient WAN connectivity
  • Implemented OMP route distribution and control policies for intelligent path selection and failover
  • Delivered training sessions for team members covering SD-WAN operations, day-to-day management, and troubleshooting procedures

Lab Project

Enterprise Campus Network Design

Designed and implemented a multi-layer campus network architecture using Cisco Catalyst switches with full redundancy and high availability.

  • Built a 3-tier campus architecture — access, distribution, and core layers using Catalyst switches
  • Configured HSRP/VRRP for gateway redundancy and EtherChannel for link aggregation
  • Implemented OSPF for dynamic routing and STP tuning for loop-free L2 topology
  • Deployed VLANs, inter-VLAN routing, DHCP services, and port security across the network
