• Maintain application lifecycle management pipelines for SPFx and Power Platform solutions in Azure DevOps or GitHub.
Operations and support • Resolve development/operations-related ServiceNow tickets to the response and resolution targets for their priority, and record disposition on the ticket at the time work is performed.
• Continually analyze web components and parts, navigation and load time, and modify components that are not performing properly or do not meet agency web standards.
• Assist in the evaluation of new tools and upgrades to maintain or improve the environment.
Program support • Agile delivery in two-week sprints, including sprint review presentation to a Government customer.
• Working in a formally change-controlled environment with board approval, maintenance windows and back-out planning.
• ServiceNow for incident, request and change records.
• Clear technical writing and the ability to explain a design decision to a non-technical Government stakeholder.
