What changed, and what it produced

Segmenting plant and office traffic, fixing warehouse Wi-Fi that failed once the racking was loaded, and documenting an estate nobody had a diagram for.

One shipment record generating the commercial invoice, packing list and customs declaration — removing a senior administrator's entire morning per consignment.

Discovering that four years of nightly backups could not be recovered from, then building and rehearsing something that could.

Replacing average-case wireless design with high-density design, and segmenting a campus network that had grown without a plan.

Getting a 30-person firm from free mailboxes and unencrypted laptops to a documented security posture, because a client made it a condition of engagement.
