Data Platform Modernization & Legacy ETL MigrationTran Tien Van
Legacy ETL, brittle Airflow DAGs and an aging warehouse slow down every new report and AI project. I modernize the platform in staged slices around the workflow that blocks delivery today, so the business keeps running and value shows up early. No big-bang rewrite.
What you get
Workflow-mapped audit of your pipelines, jobs, warehouse and costs
A staged migration plan, starting with the highest-value slice
dbt models, an orchestration upgrade (Airflow or Dagster) and observability
Data contracts and tests so the new platform stays trusted
BI migration when needed, for example Tableau to Power BI
Proof
Tableau to Power BI migration tool with an AI-assisted mapping step (built for a client)
Marketo migration and lead intelligence tooling (built for a client)
Healthcare claims ETL on Airflow and AWS Glue into Amazon Athena, with a full audit and lineage table
Vendor-book ETL on Dagster Cloud
Van Data Team migrations capture 60 to 80% of the value in the first slice
Timeline: a typical engagement runs 8 to 16 weeks, delivered slice by slice.
