Welcome to my Power BI repository! 🚀
This collection showcases interactive dashboards and data stories designed to convert complex datasets into actionable business intelligence. These projects demonstrate my proficiency in End-to-End BI development, including Data Ingestion, Power Query (M), DAX modeling, and intuitive UX/UI design.
- Data Transformation: Power Query (M language)
- Modeling: DAX (Data Analysis Expressions), Star Schema, Calculated Measures & Columns
- Visualization: Advanced Charting, Slicers, Bookmarks, and Drill-throughs
- Data Sources: Excel, CSV, SQL Server
Focus: Retail Performance & Revenue Optimization
- Description: A high-level executive dashboard analyzing Amazon's sales ecosystem across various categories and regions.
- Key Insights:
- Sales Performance: Real-time tracking of total sales, profit margins, and MoM growth.
- Regional Dynamics: Geospatial analysis identifying high-value markets and logistics bottlenecks.
- Product Intelligence: Pareto analysis (80/20 rule) to identify top-selling vs. low-performing SKUs.
- Technical Highlight: Implemented complex DAX measures for Time Intelligence (YTD, QTD) and dynamic profit margin calculations.
Focus: Political Data Science & Demographic Insights
- Description: A comprehensive deep-dive into the 2024 Indian General Election results, visualizing the democratic landscape.
- Key Insights:
- Seat Distribution: Interactive map-based visualizations showing party-wise dominance across states.
- Vote Share vs. Seat Win: Comparative analysis of party efficiency and regional swings.
- Constituency Deep-Dive: Drill-through reports showing winning margins and voter turnout percentages.
- Technical Highlight: Utilized custom map visuals and multi-layered filters to handle high-density electoral data.
In these projects, I follow a rigorous BI workflow:
- Data Cleaning: Handling nulls, pivoting data, and data type standardization in Power Query.
- Data Modeling: Designing robust Star Schemas with dedicated Date Tables for time-intelligence.
- DAX Scripting: Creating scalable measures for dynamic KPIs and custom business logic.
- UI/UX Design: Implementing a "Mobile-First" or "Executive Summary" layout for maximum readability.
