Freelance senior data engineer · Netherlands (PR) · available for select work
Dewei Zhai
Enterprise-scale data platforms. Built to last, not to demo. I help teams design and run enterprise-scale datalakes (500TB–1PB) on AWS, Azure, and GCP — and increasingly, with AI in the delivery loop.
What I do
- — Datalake / Lakehouse architecture on AWS, Azure, Alibaba Cloud. Medallion, Unity Catalog, Iceberg, Snowflake.
- — Idempotent ETL & CDC pipelines that survive late data, replays, and timezone edge cases.
- — 100% IaC platforms (Terraform, CDK, CDKTF) with dev/prod parity and automated CI/CD.
- — AI-augmented delivery — bringing custom agents and harness engineering into the day-to-day.

The fastest way is a short brief. The lowest-friction way is asking my agent first — it knows my track record and will tell you whether I'm a fit before you spend time writing the email.
