At Onix, I automated the migration of 900+ Tableau workbooks from Teradata to BigQuery, reducing delivery time from 2.5 years to 9 months while ensuring data accuracy. I also developed Tableau and Power BI reporting and supported Tableau-to-Power BI migration by mapping KPIs, calculations, data sources, filters, and business logic.
At krtrimalQ CognitiveSolutions, I designed Power BI dashboards and semantic models for enterprise reporting, using Star Schema, DAX, and Power Query. I implemented row-level security and managed Power BI Service workspaces, scheduled refreshes, publishing, and secure report distribution.
Earlier, at Cognizant Technology Solutions and NebulaTechnology, I built Tableau reports and dashboards, prepared reporting data, and improved dashboard performance. My project work includes customer contact center analytics and sales performance reporting, with interactive KPI views and drill-downs.
