At EXL, I analyze and validate large enterprise datasets using Python, PySpark, Spark SQL, SQL, and Excel. I lead Parquet-to-Delta migration analysis, validate business and composite keys, and identify anomalies that affect data accuracy and performance.
Previously at TCS and TransUnion CIBIL, I improved data quality across ingestion and target datasets, built reports, KPI scorecards, and dashboards, and translated technical findings into business-friendly insights. I used SQL, Hadoop, Python, Tableau, Excel, and Power BI to detect anomalies, resolve data issues, and support finance, leadership, and data teams.
I bring 7+ years of experience in analytics, reporting, ETL, data processing, governance, and visualization, including team leadership and mentoring.
