- Parallel or distributed processing (e.g., multiprocessing, Dask, Spark, or similar).
- Performance tuning to replace or improve upon SAS I/O and batch optimizations.
- Ability to profile code and identify bottlenecks in data pipelines.
Automation & DevOps

- Experience writing unit tests, integration tests, and validation checks to ensure data accuracy and consistency.
- Ability to validate Python-based outputs against legacy SAS results when required.
Jupyter & Collaboration
