You will get a modern ETL based on your legacy SQL code
Project details
Modernize your legacy SQL logic with clean, scalable ETL pipelines. If you rely on stored procedures, views, or SQL scripts for critical data workflows, I’ll help you refactor and migrate them into maintainable, high-performance ETL code using Python, Polars, DuckDB, or Spark—built for flexibility and big data.
This service is ideal for teams transitioning from SQL Server or complex SQL logic into modern data stacks. I deliver clean, modular code with optional scheduling, config layers, and modern output formats (like Delta Lake or Parquet).
✔ Migrate stored procedures and complex queries
✔ Preserve logic, calculations, and edge cases
✔ Output to Delta, CSV, or database
✔ Optional Airflow scheduling or YAML configs
✔ Full source code and clear documentation
Perfect for data teams, analysts, and engineers managing growing workloads.
