- Solution Documentation: Create and maintain functional specifications, configuration documents, and integration mappings
- Stakeholder Engagement: Collaborate with business users, analysts, and technical teams to translate requirements into system solutions and ensure user readiness
- Cross-Team Collaboration: Work across internal HMRC teams, systems integrators (SIs), and vendors to ensure cohesive delivery and issue resolution
