At EPIC, I build reusable enterprise Power BI semantic models, interactive dashboards, and multi-source data pipelines that support scalable reporting and accurate business decisions. I work across SQL Server, SharePoint, Excel, Azure Databricks, and cloud data sources.

I develop advanced DAX measures, optimize models with DAX Studio, Tabular Editor, and VertiPaq analysis, and administer Power BI Service environments with secure publishing, scheduled refreshes, gateways, deployment pipelines, and Row-Level Security. I also use Databricks, MLflow, and Spark MLlib to prepare curated datasets for forecasting, anomaly detection, and customer segmentation.

Previously at Juniper Networks, I improved reporting efficiency by 30% through interactive Tableau dashboards, SQL optimization, SSIS pipelines, Python automation, and Tableau Server administration. At TransUnion India, I delivered Power BI dashboards, star-schema data models, SSIS workflows, Power Automate flows, and Power Apps connected to SQL Server and SharePoint.

I'm focused on translating business KPIs into governed, high-performance analytics solutions, partnering closely with business users, product owners, IT, data engineering teams, and stakeholders through requirements gathering, UAT, production support, and end-user training.
