End-to-End Data Analysis Project with Power BI (Cleaning + Visualization)

This project presents a complete data analysis workflow using Microsoft Power BI.

? Project Overview:

I analyzed a flight delays dataset to uncover key insights and patterns affecting airline performance.

? Key Features:

* Data cleaning and transformation using Power Query

* Data modeling (relationships & star schema)

* Interactive dashboards with slicers and filters

* KPIs to track delay reasons (Carrier, Weather, NAS, etc.)

* Clear and user-friendly data visualization

? Tools Used:

* Microsoft Power BI

* Power Query

? Outcome:

The dashboard helps users quickly identify the main causes of delays and monitor performance trends.

? This project demonstrates my ability to turn raw data into meaningful insights and professional dashboards.
