Real-estate & vehicle market data (OLX, Otodom, Otomoto)

The brief
Problem, approach, result.
Problem
Resellers were refreshing OLX, Otodom, and Otomoto by hand all day, trying to be first to a good listing, and still missing the best ones.
The same property or car appears across sites with different titles and prices, so even a manual list was full of duplicates.
Approach
- Built listing scrapers for all three marketplaces, handling pagination and listing detail pages.
- Fingerprinted listings to merge cross-site duplicates into a single record with a unified price history.
- Fired instant alerts when a listing matching saved criteria appeared, with the source link.
Result
One deduplicated feed replaced hours of tab-flipping, and the team is now reliably first to react to fresh listings.
Price history across sources makes it obvious when something is genuinely underpriced.
