/ THE STORY

The engagement

Production enterprise application supporting a regulated organization. Ticket-driven work — incidents, change requests, and small enhancements routed through ServiceNow with weekly delivery calls.

What I do

Triage incoming tickets, reproduce issues against the live system, ship targeted fixes through the change-management pipeline, and close out tickets with documented root cause. Combination of urgent incident work, scheduled change requests, and steady-state maintenance.

What it proves

I can plug into an existing enterprise team, work the ticket queue without supervision, and ship reliable fixes inside a regulated environment — without breaking anything around it.

/ HIGHLIGHTS

What stands out

  • Triage and close ServiceNow tickets within agreed SLAs
