ServiceNow Dashboard Development

I'm seeking an experienced ServiceNow developer to create a comprehensive dashboard. This dashboard will be used primarily by senior leaders to track IT support tickets and service performance.

The dashboard should display the following ticket details:
- Open, closed, and overdue ticket counts
- Ticket status by priority and support team
- Average response and resolution times
- Service offerings tickets triggered in the last three months
- Response and resolution SLA breach tickets

Ideal skills and experience:
- Proficiency in ServiceNow platform
- Experience in dashboard creation and customization
- Strong understanding of IT service management metrics
- Ability to present data in a clear, concise manner for senior leadership consumption

Please provide examples of previous ServiceNow dashboards you have created.
