Role: Python Automation & Data QA
Synthetic portfolio-process case that normalizes eight source rows into five reviewable master rows while keeping ambiguous records visible.
The workflow uses exact-key normalization, duplicate controls, exception routing, a change log, reproducible tests and deterministic output packaging.
This is not client work and does not claim time savings, revenue lift or another commercial result.
