About Macarena

I support organizations in designing and delivering SAP S/4HANA transformation programs across manufacturing and supply chain environments, with a strong focus on solution architecture, master data consistency, and end-to-end process integration.

With 15+ years of experience as SAP Solution Architect and Senior IT Project Manager, I lead initiatives spanning solution design, system integration, and deployment across complex landscapes, including ERP–PLM–MES ecosystems.

My expertise lies in aligning engineering, manufacturing, and supply chain processes, ensuring seamless data flows between PLM and SAP, and enabling scalable, harmonized solutions for global operations.

I bring a pragmatic, delivery-oriented approach to architecture, combining hands-on program leadership with a strong understanding of SAP Supply Chain processes (MM/WM/PP/QM/DMS) and their role in manufacturing environments.

I typically support organizations in SAP rollouts, system integrations, and transformation programs, with a focus on operational efficiency, business value, and user adoption.
