Power BI Developer transforming data into secure, high-performance dashboards using DAX, SQL, Snowflake, and Azure.
IndiaWhat I'm looking for
I’m a Power BI Developer with 3.4+ years of experience building enterprise dashboards and paginated reports. I specialize in Power BI (Desktop/Service), DAX, data modeling, Snowflake, ETL, and Azure to improve reporting efficiency, data accuracy, and decision-making.
At Tata Consultancy Services (TCS), I created on-demand data models and interactive visuals, improving data accessibility by 25%. I migrated dashboards into Power BI, reducing manual effort by 15%, acted as the SQL POC to ensure 100% data accuracy, and improved query performance by 30% through optimized DAX, SQL views, and performance tuning.
I also lead large-scale migrations, including IBM Cognos to Power BI, where I built star-schema models, implemented RLS for secure role-based access, and tuned PowerQuery/Dataflow ETL pipelines for stability. With a strong focus on unit testing, UAT, and defect-free deployments, I consistently deliver reliable reporting and earn recognition for performance and problem-solving.
