Marielle Miziara

@mariellemiziara

I turn financial and operational data into reliable dashboards, diagnoses, and recommendations.

At Mosaic Fertilizantes, I consolidate SAP, Excel, and SharePoint data to analyze accounting closing, reconciliations, payments, taxes, assets, SOX, and targets. I investigate inconsistencies and deliver reports with conclusions and recommendations for users and leadership.

I've built 5+ daily-updated Power BI dashboards for 30+ users across four areas, using star schemas, Power Query, DAX, dataflows, incremental refresh, and access controls. I also teach SQL, relational modeling, and Power BI at FAT Educacional, and built an ecommerce data platform that reconciled values across 9,997 orders.
