This folder contains my interactive dashboards and analytical reports developed with Power BI, focused on business intelligence, performance metrics, and data storytelling.
Each report demonstrates end-to-end analytical capabilities — from data cleaning and modeling to visual design and insight communication.
To demonstrate my ability to turn data into actionable insights through every stage of the analytical process:
- 🧹 Data Preparation: Cleaning, transforming, and normalizing raw data in Power Query.
- 🧩 Data Modeling: Building structured, efficient star-schema models with clear relationships (1→*).
- 🧮 DAX & KPIs: Creating calculated columns and measures to track performance, trends, and key metrics.
- 📊 Visualization & Storytelling: Designing clear, interactive dashboards aligned with real business questions.
- 🧠 Analytical Thinking: Interpreting data to identify drivers, patterns, and opportunities for improvement.
- ⚙️ Performance Optimization: Ensuring fast queries, clean models, and scalable designs.
- 💬 Communication: Presenting findings visually and contextually, helping decision-makers act with confidence.
Each dashboard reflects a consistent analytical approach — combining technical precision, business understanding, and visual clarity to support informed decisions.
The dashboards are designed to help organizations transform raw data into meaningful stories and strategic decisions.
