At Axis Bank, I support the Credit Card Portfolio team by analyzing portfolio performance and business data. I validate and reconcile datasets, then prepare reports and dashboards in Microsoft Excel and Power BI.

At DT Travels PVT/LTD, I maintained and verified customer, booking, vendor, and transaction records in Excel. I also prepared operational reports and assisted with commission calculations and reconciliation.
