About

If your data is sitting in spreadsheets without telling you anything useful, that's the problem I fix. I'm Sanjay, a Data Analyst at Fluentgrid Limited, where I work with SQL, Power BI, Excel, and Python to turn raw, messy data into dashboards and reports that help teams actually make decisions not just look at numbers. Over the past couple of years, I've worked across operations, risk analytics, and business intelligence. At WNS, I conducted root cause analysis on driver risk data and built performance tracking systems that kept quality benchmarks above 96.5%. At AtliQ Technologies, I handled data cleaning and transformation on 1M+ records and built Power BI dashboards that improved decision-making efficiency by 40%. Right now at Fluentgrid, I work on ETL processes, data modeling, and ad-hoc analysis while building interactive dashboards and KPI reports that help teams make faster, data-driven decisions. Outside of work, I create data analytics content on LinkedIn for 4,500+ followers breaking down SQL, Power BI, and Excel concepts in ways that are easy to understand. It keeps me sharp and helps others break into the field. What I bring to any team: → SQL >> CTEs, Window Functions, complex joins → Power BI >> dashboards, DAX, data modelling → Excel >> Power Query, Power Pivot, advanced reporting → Python >> Pandas, NumPy, EDA → Others >> ETL, Data Cleaning, RCA, KPI Reporting, Stakeholder Management You can explore my work and projects at: https://codebasics.io/portfolio/Sanjay-Polamarasetti I'm always open to connecting with data professionals, recruiters, and anyone working at the intersection of data and business decisions.
