🚀 About Me

As a Data Scientist and Kaggle Master (Rank 109), I go beyond data visualization to solve concrete business problems. This collection showcases my Power BI dashboards, where every project is built upon a structured 'Data-to-Decision' framework.

  1. Semantic Modeling: Cleaning, transforming, and modeling raw data.
  2. Advanced DAX: Creating dynamic measures for complex calculations.
  3. Storytelling: Designing dashboards that drive decision-making.
  4. Business Impact: Identifying the "So What?" and recommending strategic actions.

🛠️ Tech Stack & Skills

  • Core: Power BI Desktop, Power BI Service, DAX, Power Query (M).
  • Data Sources: SQL, Excel, CSV, Web APIs.
  • Focus Areas: Healthcare & Life Sciences, Finance & Banking, Retail & E-commerce, Marketing & Consumer Analytics.
