IT Operations Leader · Bothell / Seattle

Robert
Casto

IT operations built to scale—and measured to prove it.

I lead service delivery, infrastructure, identity, security and endpoint operations. In sixteen years I have raised SLA performance from 76% to 96%, managed $5M in IT spend, and supported fleets of 1,000+ endpoints.

Operational change
you can measure.

The work ranges from stabilizing daily service to scaling global operations. The common thread is a clear baseline, a system people can follow, and an outcome the business can see.

Built where no product
met the requirement.

Each of the following began as an operational problem in one of my roles.

saasguard

Aircall had no single view of which SaaS applications were in use, what they cost, or which accounts remained active after offboarding. saasguard reads Microsoft Graph and Entra ID and reports all three in one dashboard.

Floorcraft

Desk assignment across a multi-floor office exceeds what a spreadsheet can hold once hoteling, hybrid schedules and multiple sites are involved. Floorcraft makes the floor plan the source of truth and tracks every reassignment.

slack-buddy

A conversational assistant for recurring IT questions that do not warrant a ticket. It answers within Slack, where staff already work.

The platform dashboard

Built for Eastside Exterminators so that runbooks, procedures and current platform state are available to the team directly. Documentation that requires a request to reach it does not serve its purpose.
