Each engagement begins with an agreed scope and clear deliverables. Customers receive direct technical communication during the work and documentation they can use after the engagement is complete.
The examples below describe selected engineering work performed through independent consulting. Each project states its attribution; client and employer details are omitted or generalized where appropriate.
Success story 1
District-wide school modernization
Independent consulting engagement — anonymized for confidentiality.
The challenge
A district running an undocumented legacy Extreme Networks stack — switches, controllers, and access points — due for replacement.
The role
Senior network engineer, from full discovery through migration and documentation.
The scope
8 schools and the district office — roughly 65 switches and 380 access points; a FortiGate acting as controller for switches and APs; full discovery of the existing VLANs, inventory, and port configurations.
DiscoverMapped the existing network: VLANs, switch inventory, port configurations, and the current Layer-2 topology.
2
DesignSpecified the Fortinet stack and the migration order, working with site IT.
3
MigrateImplemented the stack in stages: configuration, cutover, and troubleshooting through the transition.
4
DocumentDelivered complete Layer-2/Layer-3, port, and network documentation so site IT could run the network day to day.
The deliverable: a working, documented Fortinet estate across all 8 schools and the district office, with the Layer-2 documentation handed to the client.

Success story 2
Public transit authority network migration
Independent consulting engagement — anonymized for confidentiality.
The challenge
A multi-site transit authority running a Cisco network needed to modernize routing, switching, security, and wireless across its operational footprint.
The role
Senior network engineer, from current-state discovery through migration and documentation.
The scope
Migrating the authority's sites from Cisco to a cloud-managed Meraki stack, and documenting the result at Layer 2 and Layer 3.
Technologies
Cisco (legacy) → Meraki (MX, MS, MR) and SD-WAN.
How we delivered it
1
DiscoverMapped the current Layer-2 and Layer-3 topology across the sites.
2
DesignPlanned the Meraki stack, VLAN/subnet layout, and migration order.
3
MigrateImplemented the stack in stages, with cutover and troubleshooting.
4
DocumentDelivered Layer-2 and Layer-3 as-built documentation for the operations team.
The deliverable: the migrated, documented Meraki network, with Layer-2 and Layer-3 documentation handed to operations.
