The brief
Pricing analysts needed a clean, daily view of sixty thousand competitor listings across five marketplaces — spreadsheets copied by hand were already wrong by lunchtime.
What we built
A Playwright grid that rotates through the five marketplaces with polite rate limits
Normalisation into one product model: currency, VAT, shipping and variant matching
Anomaly alerts when a competitor moves price more than a set threshold
Nightly loads into the warehouse with full run history and replayable failures
