Custom Price Monitoring Systems
I build price monitoring systems: track price changes across many sellers and products, detect anomalies, store history, and alert when prices move. Based on my experience building cenoskop.sk and niftycent.com.
What I Can Help With
Build price monitoring infrastructure for products/sellers.
Typical Problems
Relevant Experience
Built the price monitoring system for Cenoskop — tracking price changes across 500+ sellers and millions of products, with change detection, history storage and configurable alert thresholds. Also built Niftycent's US market monitoring pipeline.
What Is Included

Frequently Asked Questions
How often should prices be rechecked?
Depends on your domain — I help you pick a cadence per seller that balances freshness against crawl load.
