• Own executive communications such as program narratives, reviews, dashboards, and status updates for senior stakeholders.
• Track program health, maintain risk registers, and drive action plans to keep initiatives moving forward.
• Build alignment across engineering, operations, finance, security, and leadership teams without relying on direct authority.
