About
Software engineer building open-source matching tools — and the SaaS funnel that wraps them.
I created the Golden Suite — five Python libraries for checking, transforming, matching, and orchestrating data. Each works standalone, or together as the engine inside bensevern.dev: the matching funnel between your SaaS sources and your warehouse. We collect, match, surface ambiguous clusters for review, and push the resulting golden records out. The customer keeps their data; we're the filter, never the source of truth.
GoldenMatch also ships native Rust kernels (goldenmatch-native), a TypeScript build (goldenmatch-js), and a Postgres extension (goldenmatch-pg).
Open Source Data Tools
Building tools that check, transform, match, and map data. All open source. All production-grade.
A technical look at how the /cleanroom tool finds the overlap between two lists using Bloom-filter fingerprints (CLKs), why the server can't reverse them, and how the browser tier keeps raw data on your device.
A knowledge graph is only as good as its entities. Why bad entity resolution wrecks KG quality and cost, and how GoldenMatch solves the node layer.
Most MDM tools want to be your source of truth — you query their store. bensevern.dev inverts that: it's a matching funnel between your SaaS sources and your warehouse, then hands the data back. Here's what that looks like end-to-end.
