Automated Lead-Generation Engine

The businesses that most need a website are the ones you can't easily find — they don't show up in search, they don't run ads, and they rarely appear on the lists a consultant would normally scrape. Building a prospect list for them means clicking through map apps one business at a time, copying names into a spreadsheet, and hoping you don't lose track halfway through.

That manual loop is exactly the kind of work that doesn't get done. It's slow, it's easy to abandon, and by the time a list exists, the moment to reach out has usually passed. The goal of this engine was to remove the loop entirely: point it at a city, walk away, and come back to a finished, qualified list.

The engine reads from OpenStreetMap's node API and Foursquare's public listings. Where a business has an OpenStreetMap node, the phone, opening hours, and cuisine tags are pulled straight from the record — verified data, not inferred. Businesses that only existed in Foursquare's listings still make the cut, but are flagged as source-only so the record is honest about what's confirmed.

Designing the 18-field schema and the resumable writer before any enrichment ran was the key decision. Because every row is written and flushed immediately, an API outage or a dead laptop mid-run doesn't corrupt the file — the next run skips what's already there and continues. The final QA pass confirmed 100% coverage with zero duplicates.
