Lead discovery sessions to understand current-state platforms, business objectives, compliance drivers, user impact, and migration dependencies.
Work with project management and delivery teams to ensure migration plans, milestones, risks, and technical deliverables remain aligned and executable.
Develop practical migration approaches that address mailbox, file, collaboration, identity, device, and security workloads with minimal business disruption.
Support pilot migrations, user readiness activities, cutover events, and post-migration issue resolution.
Create and maintain clear technical documentation, runbooks, configuration records, and transition materials for implemented solutions.
Participate in sales discovery to validate requirements, shape scope, identify assumptions and risks, and recommend migration strategies for Modern Work engagements.
Review and provide input on Statements of Work (SOWs) for technical accuracy, migration feasibility, assumptions, risks, and acceptance criteria.
Partner with Sales and Project Management from pre-sales through delivery to ensure the engagement is set up for a successful outcome.

Maintain familiarity with structured delivery methodologies and adapt to fast-paced customer environments with strong judgment and just-in-time learning.
