Core Data Unification

One source of truth, not three systems that disagree.

Three systems that each think they're right isn't redundancy, it's risk. This makes them agree.

What it does

Merges core, loan origination, and third-party data into a single trustworthy source, so downstream reporting and models are not built on reconciled-by-hand exports.

What this demonstrates

Designing a data unification layer across systems that were never built to talk to each other, with the reconciliation logic that makes one source trustworthy.

Curious how this was built?
