Problem

The operating gap

The agency had accumulated a massive historical lead database across multiple sources — ad platforms, cold outreach lists, CRM exports, and third-party data vendors. The data was dirty: duplicates across sources, inconsistent field formats, incorrect timezone assignments, and outdated contact details. Running campaigns against this data was producing poor results and wasting ad budget. Manually cleaning it was estimated to take weeks.

Build

What gets built

Built a data pipeline pattern for deduplication by contact fingerprint, field normalization, timezone assignment, quality scoring, direct CRM ingestion, segment tagging, recurring delta runs, and reporting by source quality.

Build steps

How it ships

Large Data Cleanup Pipeline Blueprint uses a reporting model and review layer for Dashboards. A privacy-safe data pipeline pattern for cleaning, deduplicating, scoring, and importing lead records before they enter an active CRM. The architecture connects capture large data cleanup, python scripts, postgresql, and dashboard action with an explicit control path.
