What I'm looking for

I'm looking to build reliable data pipelines, dashboards, and reporting solutions that help teams make data-driven decisions and improve operational processes.

I've built Power BI and Apache Superset dashboards at Sreenivasam Infotech LLP to turn operational and infrastructure data into actionable KPI reporting, asset-tracking insights, and capacity-planning visibility.

I design ETL workflows with Power Query, clean and transform large datasets, and build data models with DAX calculations for SLA compliance, performance metrics, and variance analysis. My automated refresh schedules and data pipelines improved reporting efficiency by 30% while reducing manual reporting effort.

I also write complex SQL using joins, aggregations, CTEs, window functions, and query optimization techniques. I validate dashboards, verify KPI accuracy, document source-to-target mappings, and collaborate with cross-functional teams to turn business requirements into reliable reports.

Beyond BI, I've applied Python, statistical analysis, and machine learning to predict COVID-19 case trends, and built an image-to-cartoon application with Python and OpenCV.
