Message

At Fujitsu, I built and maintained more than 20 interactive Power BI dashboards to help teams monitor operational and supply chain risks and make informed decisions. I also built ETL pipelines that brought data from sources including SAP and Salesforce into structured outputs, reducing manual preparation time by 30%.

At Continental, I created KNIME workflows for supply chain analysis and developed Power BI dashboards from supplier capacity and manufacturing demand data. I also forecast demand and applied probabilistic inventory models, contributing to an estimated 15% reduction in inventory holding costs.

Earlier, at Laureate Education, Inc., I developed Tableau dashboards and Excel reports tracking student learning experience, retention, and employability across universities. My background combines industrial and systems engineering, automotive management, and postgraduate study in statistics and data science.
