Senior Data Engineer

I build data platforms and batch and streaming pipelines on GCP with Airflow and BigQuery. At ABACUS digital I built the cloud landing zone solo: Terraform/Terragrunt, network, IAM, security, and the data platform on top of it. I optimize for maintainability and repeatability: tests that fail first, automation so no one has to remember, patterns that make the next one cheaper.
