In my sales analysis project, I cleaned and validated transaction and customer records using Python and Pandas, then wrote SQL queries for product-wise, monthly, and regional sales reports. I also built Excel dashboards to track sales KPIs and identify underperforming segments.

For my customer billing and payment data quality project, I used SQL and Pandas to investigate duplicate transactions, missing payments, mismatched amounts, and outstanding bills. Excel pivot tables and conditional formatting helped track and highlight discrepancies.

During my Data Analysis using Python internship at ExcelR EdTech in collaboration with APSCHE, I worked with Pandas and NumPy on data cleaning, transformation, and exploratory analysis. I also built a supervised model for IoT network intrusion detection and used SHAP and LIME to explain its predictions.
