PolkLookup — Property Records (Mobile + Web)
What they needed
Polk County, FL publishes property records on a search interface that requires an internet connection, returns one record at a time, and is slow to traverse for anyone doing field work or batch lookups. There was no offline option, no fuzzy matching across owners and addresses, and no way to use the data in a browser without round-tripping every query.
What I built
Two artifacts solving one problem. The React Native app on Expo bundles the dataset into Expo SQLite and runs queries fully offline with fuzzy owner / address matching. The browser app uses sql.js to load the same SQLite database into WebAssembly and run queries in-memory in the browser — no backend, no API rate limits, no per-query roundtrip. Both handle the upstream HTML scraping and parsing through cheerio so the dataset stays current.

What it does now
Try it — live property search
This box runs a 5,000-address slice of the live 310k+ record dataset — the same SQLite engine the real app uses, compiled to WebAssembly and querying entirely in your browser. Type a street name and watch it search with nothing on the other end.
