Hire the Best Network Engineers
in Canada

Network Consultant | TAC Engineer | Routing, MPLS, VPLS | Network Security Specialist I am a Network Consultant and former TAC Engineer with a Master of Engineering in Internetworking from Dalhousie University, bringing strong hands-on experience in designing, deploying, and troubleshooting complex network infrastructures. I currently work at Ciena delivering advanced network solutions in routing, switching, and service provider environments. Previously, I worked at Fortinet as a TAC Engineer, where I handled critical network security cases across enterprise and service provider customers. I specialize in building networks that are not just functional, but scalable, resilient, and production-ready. What sets me apart is field experience. I actively work on real network deployments, not just lab simulations. I understand how designs behave under real traffic, failures, and operational constraints, and I bring that insight into every project. I also have extensive experience building multiple network projects in GNS3 and Packet Tracer, simulating real-world topologies for design validation, troubleshooting, and training purposes. Services Offered Network Design and Simulation End-to-end network design using GNS3 and Cisco Packet Tracer Realistic lab environments for testing, validation, and training HLD and LLD Documentation Professional High-Level and Low-Level Design documents Visio diagrams with deployment-ready configurations Routing and Switching Solutions Design, implementation, and optimization of core and edge networks Advanced troubleshooting for production issues VPN and Security Solutions Secure VPN deployments and troubleshooting End-to-end security policy design and implementation NAT and Traffic Engineering Advanced NAT design and troubleshooting for complex environments Network Troubleshooting and Analysis Deep packet analysis using Wireshark Root cause analysis for complex network issues Training and Visual Learning CCNA and networking training with a strong hands-on approach Step-by-step lab guidance using GNS3 and Packet Tracer Visual learning using diagrams, topology breakdowns, and real traffic flow explanations Concept simplification using practical scenarios instead of theory-heavy teaching Interview preparation and real-world troubleshooting mindset I bring a consulting mindset to every engagement. I do not just fix issues, I design solutions that prevent them. Whether you need help with a lab, production network, troubleshooting, training, or full-scale design, I deliver results that are practical, efficient, and aligned with real-world operations. If you are looking for someone who understands both theory and production networks, let’s connect.
