I’m a GCP Data Engineer with hands-on experience building and running large-scale data pipelines using Dataproc (Spark), BigQuery, and Apache Airflow. My core work revolves around: Dataproc clusters for heavy transformations using PySpark Spark → BigQuery migrations and performance tuning Handling UDF-heavy and compute-intensive workloads where BigQuery alone isn’t sufficient Airflow / Cloud Composer for orchestration and dependency management Writing production-grade Python & PySpark code Designing denormalized datasets for analytics and reporting
