You will bridge business needs and technical solutions, ensuring the migration delivers operational efficiency, regulatory compliance, and an improved customer experience across impacted portfolios.
Additionally, you'll elicit, document, and validate detailed business requirements relating to customer data, product portfolios, and end‑to‑end workflows.
