What I did, and what changed.

• Segmentation

  14-VLAN network segmentation

  I designed a 14-VLAN segmentation architecture and paired it with Fortinet firewall controls and remediation.

  Identified vulnerability exposure dropped by approximately 60%.

• Performance

  Network redesign and wireless optimization

  I led a network redesign and wireless optimization, including access point placement and channel planning.

  Overall network performance improved by approximately 50%.

• Uptime

  Failover cluster and Microsoft 365 migration

  I led the move to a three-host Hyper-V failover cluster on SAN storage and the migration from Exchange to Microsoft 365. I coordinated vendors, service providers, and internal teams through each upgrade and rollout.

  Approximately 40% better service uptime and approximately 90% less email downtime.
