I am a GCP Data Engineer with 4+ years of experience in building scalable ETL pipelines, data lakes, and data warehouses. I specialize in SQL, Python, PySpark, BigQuery, Dataproc, Dataflow, and Airflow, and have worked across retail, pharma & Healthcare domains delivering business-driven data solutions. On Topmate, I guide students and professionals who want to learn data engineering from basics to advanced, including real-time project workflows like ingestion from GCS, transformations in PySpark, and orchestration with Airflow. If you’re looking to build a strong foundation in data engineering, cloud (GCP), and big data, or need career guidance, interview preparation, and project explanations, I’ll help you with step-by-step learning and practical examples.
