• Expert‑Level Technical Support: Serve as the primary escalation point for complex administrative and technical challenges, providing expert‑level troubleshooting and resolution with minimal disruption to senior‑leader operations.
• Training and Mentorship: Lead the development of the SharePoint training program. Design and deliver targeted training on advanced functionalities and mentor DASA DE&C staff.

  • Expert proficiency in designing and implementing solutions using the Microsoft Power Platform.
  • Proven ability to engage confidently with senior stakeholders, understand mission context, and translate complex business needs into robust technical requirements.
