Data Analyst | Data Cleaning, Data Processing & Insight Generation from Excel/CSV Data

Working on data analysis of large-scale toll transaction datasets generated from public transport buses.

Built a structured data analysis system to monitor and analyze FASTag toll transactions across hundreds of buses and thousands of daily transactions.

The system helps identify anomalies such as duplicate toll deductions, irregular toll activity, and potential fraud patterns between toll plazas and service providers.

I designed automated workflows for cleaning raw Excel/CSV data, validating records, and extracting actionable insights to support operational monitoring and decision making.
