Overview

A document-automation workflow for assembling structured data-access outputs from validated source information. The goal was to reduce repetitive manual formatting while preserving reviewability and traceability.

The problem

Data-access workflows can require gathering information from multiple sources and converting it into a user-facing document. Repetitive copying creates avoidable formatting errors and makes consistency difficult to maintain.

Design priorities

Separate raw source information from presentation logic
Make missing fields visible rather than silently filling gaps
Preserve a predictable document structure
Keep final review with a human operator

Privacy by design

The public portfolio contains no real data, credentials or internal business logic. Demonstrations should use synthetic records and a simplified schema.

What I learned

The project highlighted how much legal and privacy work is ultimately information transformation: collecting, validating, structuring and presenting data under explicit rules. Automating that transformation is useful only when the provenance of the information remains clear.
