Why it exists
CRM migrations can fail on small differences in field names, phone formats, tags, and import limits.
Portfolio / CASE STUDY
Private data migration tool
FUB to Sierra CSV Converter.
A tool for previewing and transforming Follow Up Boss contacts into Sierra CRM import files.
MY ROLE
Independent converter and web workflow development
What I built
I built a deterministic mapping and normalization pipeline, then wrapped it in a browser upload, preview, and download workflow.
Project in view
Engineering decisions
Normalize before exporting
The converter maps source fields to the target schema, formats phone values, and deduplicates tags. Unit tests cover the transformation rules.
Plan for large imports
Large outputs can be split into bounded chunks and bundled for download. Users can inspect the preview before exporting.
Test the round trip
Integration and upload/download tests exercise the flow from fixture data to converted output. The web app also includes cleanup for session files.
Capabilities in practice
- Schema mapping
- Data normalization
- Import tooling
- Integration testing
Status & scope
Private migration utility with synthetic example data and tests. I can discuss the conversion rules and test strategy on request.
