About Ousseina

Senior IT Integration Manager with over 10 years of experience leading complex SAP S/4HANA transformation programs in international environments. I specialize in IT integration, ERP transformation, data migration, master data governance (MDG), cutover planning and cross-functional coordination.

I have successfully delivered large-scale transformation projects for global organizations in the pharmaceutical, manufacturing and industrial sectors, working closely with business stakeholders, IT teams, system integrators and external partners to ensure successful deployments.

My expertise covers end-to-end SAP S/4HANA implementations, integration governance, data migration strategy, testing coordination (SIT/UAT), cutover execution, risk management and stakeholder alignment. I bring a strong understanding of Finance, Procurement, Supply Chain and Master Data processes, enabling me to bridge business and IT throughout transformation programs.

I am recognized for my ability to coordinate multidisciplinary teams, manage complex dependencies, drive decision-making and deliver high-quality results in fast-paced international environments.
