At Telus Digital, I design and maintain BigQuery ETL pipelines that process 90K+ structured and unstructured records daily. I also built a real-time streaming pipeline using Apache Kafka, GCP Dataflow, and PySpark, with analytical data in BigQuery and operational data in Cloud SQL.
I improved BigQuery query performance by 40% through partitioning, clustering, and SQL optimization, and reduced data errors by 30% with validation and deduplication. I also built a RAG-based AI knowledge assistant on Vertex AI to support onboarding and shared technical knowledge with junior team members.
