Ahmed Marzouk developed an end-to-end Airflow-based ETL pipeline for the omar-gamal99/talabat_bootcamp repository, enabling automated data movement from PostgreSQL to Google Cloud Storage and BigQuery. He designed and implemented a new Airflow DAG in Python to orchestrate extraction, transfer, and loading processes, addressing both data flow and storage configuration. Ahmed improved reliability by fixing syntax in extraction scripts, correcting BigQuery table naming, and standardizing GCS bucket and file names. His work reduced manual intervention and improved data consistency, demonstrating practical data engineering skills in Airflow, Python, and cloud storage while delivering a maintainable, production-ready analytics pipeline.

In May 2025, delivered an end-to-end Airflow-based ETL pipeline for omar-gamal99/talabat_bootcamp, enabling reliable data flow from PostgreSQL to Google Cloud Storage and BigQuery. Implemented a new Airflow DAG to run a Python function and orchestrate the complete ETL process, including data transfer to GCS and loading into BigQuery. Accompanied by targeted fixes to the data transfer DAG and storage naming/configuration to improve reliability and maintainability (syntax fixes in extraction, corrected BigQuery table naming, clarified DAG naming, and standardized GCS bucket/file naming). These changes reduce manual intervention, improve data consistency, and accelerate analytics readiness.
