04Selected Work

Four case studies, one question each.

Each project starts with a business problem someone actually had — then walks through the modelling, the visuals, and the answer.

01/Case StudyPower BI

Sales Data Analysis

Revenue clarity, one dashboard.

Problem · Revenue teams lacked a single source of truth to spot underperforming products and regions in real time, slowing weekly planning.

Approach · Built an interactive Power BI dashboard with DAX measures that surfaces sales trends, KPI variance, and product/region drill-downs at a glance.

02/Case StudyPower BI

Insurance Data Analysis

Reading risk from the claims log.

Problem · Insurance teams struggled to identify risky claim patterns and the most profitable customer segments inside fragmented spreadsheets.

Approach · Modeled claims and customer data in Power BI with DAX so analysts can isolate claim frequency, risk drivers, and profitability bands in seconds.

UPI Transactions Analysis

Volume tells half the story.

Problem · Digital-payment operators needed to read transaction behaviour across merchants and regions — not just total volume.

Approach · Built Power BI reports that decompose transaction volume, growth, and merchant-level performance into a single navigable view.

Student Depression Analysis

Survey data that finally talks.

Problem · Mental-health survey data was scattered and hard to interrogate for demographic patterns that policy teams care about.

Approach · Cleaned and reshaped the dataset with SQL, then visualised lifestyle and demographic correlations in Tableau so non-technical stakeholders can read the signal.
