At MERCADONA, I gather business requirements and write functional specifications for SAP MM and SD improvements. I coordinate development follow-up, manage releases with SAP Solution Manager Focused Build, and support functional testing and incident resolution.
I also work on migrations from legacy systems to standard SAP S/4HANA, validating data quality and analyzing iDocs and interfaces. Previously, at EDICOM, I implemented EDI document-exchange protocols and programmed Java and JavaScript processes for data integration.
