architecture documentation, and technical design specifications.
Network Segmentation & Security
Design and implement logical network segmentation to improve:
Security
Compliance
Device isolation
Traffic management
User and device visibility

Update network services impacted by the current IP schema including:
DHCP
DNS
VLAN configurations
Routing tables
Network monitoring systems
Develop migration plans that minimize user and application downtime.
Implementation & Project Delivery
Develop a phased implementation plan and migration strategy.
Coordinate network changes with IT infrastructure, security, systems, and operations teams.
Lead network deployment activities including testing, validation, cutover, and post-implementation support.
Create rollback procedures and risk mitigation plans.
Verify network performance and stability following implementation.
Operational Support
Provide advanced troubleshooting and root-cause analysis for network-related issues.
Support Cisco-based network infrastructure including switches, routers, wireless systems, and firewalls.
Establish network standards, monitoring practices, and operational documentation.
Mentor junior network engineers and provide technical guidance when needed.
