As a trainee data engineer with a focus on Google Cloud Platform (GCP), I have gained extensive knowledge in GCP services, Python programming, and SQL. My hands-on experience includes working with key GCP tools such as BigQuery, Dataflow, and Cloud Functions.Specifically, I have:Developed and optimized Dataflow pipelines: I have designed and implemented both batch and stream processing pipelines using Apache Beam within Dataflow, enabling efficient data transformations and real-time processing.Built and deployed Cloud Functions: I have created serverless functions that respond to events and integrate seamlessly with other GCP services. This experience has allowed me to automate workflows and handle data ingestion tasks effectively.Leveraged BigQuery for data analysis: I have performed complex queries, managed large datasets, and utilized BigQuery's capabilities for data warehousing and analysis. This includes optimizing query performance and applying advanced SQL techniques.
