    paper Freelance Data Engineer | Azure Big Data Architectures & ETL Pipelines

    In a world where data management and analysis have become crucial, having a reliable and well-structured infrastructure is a major asset. This project implements a complete Big Data architecture, inspired by the Medallion Architecture, for processing and analyzing real estate transactions in France.

    The objectives are to:
    ✅ Ingest open data on real estate transactions
    ✅ Transform and clean data through ETL pipelines
    ✅ Store structured data in a Data Warehouse
    ✅ Analyze and visualize trends using an interactive dashboard

    🏗 Project Architecture
    The architecture follows the Medallion approach (Bronze, Silver, Gold) to structure and ensure data reliability.

    Bronze Layer: Ingestion of raw data from open data sources

    Silver Layer: Data transformation, cleaning, and enrichment

    Gold Layer: Final storage optimized for analytics and visualization

    ⚙ Technologies Used

    Languages: Python, SQL

    Orchestration: Azure Data Factory

    Data Processing: Apache Spark

    Storage: Azure Data Lake Gen 2, Azure Synapse Analytics

    Visualization: Power BI
