CRM Cleanup & Enrichment for ~20,000 Contacts

The challenge
Event Atlas needed cleaner contact and company records for reliable segmentation and follow-up.

What I built
I used n8n and REST APIs to automate deduplication, match contacts to companies, assign primary companies, and enrich contact records with LinkedIn URLs.

The result
The workflow improved CRM data quality across roughly 20,000 contacts and reduced manual research. The contract ended with a 5-star client review.
