I’m a data and master data analyst specializing in SAP MDG/S/4HANA governance, migration, and AI-driven analytics.
South AfricaWhat I'm looking for
I’m a data and master data analyst with 15+ years’ experience turning fragmented, inconsistent data into reliable, decision-ready insight across SAP environments, finance and global operations. I specialize in master data governance (SAP MDG / S/4HANA), data migration, data quality and workflow automation.
I combine hands-on technical capability—SQL, Python, R, advanced Excel/VBA, Power BI—with sharp commercial judgement in financial analytics, including credit exposure, forecasting and investment appraisal. I also use modern AI platforms (Claude, ChatGPT, Google AI Studio) to build automated data-cleaning tools, reporting pipelines and scalable analytical workflows.
In my latest role, I govern customer master data in SAP MDG (S/4HANA Fashion), owning end-to-end validation, approval routing, documentation and audit trail workflows. I’ve designed and built VBA-based Excel automation that cut ~200 hours of manual effort with 100% output accuracy, and led UAT and end-to-end testing for stable go-lives.
I’m at my best bridging data, governance and business outcomes—re-engineering SAP financial data to analyze £270M+ global exposure, resolving legacy data-quality issues with offshore teams, and delivering dashboards and business cases aligned to structured approval frameworks.
