Enterprise Network Design & Architecture

This section showcases my foundation as a Network Engineer — routing, switching, VLAN segmentation, WAN connectivity, VPN design, firewall policy, and real-world physical/logical network architecture. All diagrams are fully recreated and sanitized for public demonstration.

⚡ Physical Connectivity Diagram

This is a fully documented physical network diagram representing a multi-site enterprise network with VLAN segmentation, VRFs, WAN circuits, firewall zones, and dual-homed router paths. It demonstrates my ability to design, interpret, and implement production-grade network infrastructures.

🔧 Technologies Demonstrated

• Layer 2/3 Switching (Cisco)
• VLAN & Subnet Design
• High Availability Routing & Redundancy
• Firewall Zoning & Policy Structuring
• Site-to-Site VPN (IPSec)
• Enterprise WAN Architecture
• Network Documentation & Diagramming
• Network Monitoring & Visibility Fundamentals

📚 What This Proves

This project establishes my baseline as a **senior-level network engineer** with the ability to:

• Design full-stack enterprise networks
• Build core routing, switching, segmentation, and security models
• Translate physical connectivity into logical architectures
• Create documentation used for engineering turnover and audits
• Build repeatable designs for enterprise or government environments
