Could you build this?

Partial While the web app is a simple price comparison directory, continuously scraping Polish DIY retailers and building accurate entity-resolution algorithms to match identical building supplies across different vendor catalogs requires serious data engineering.

What it would actually take: The system requires a Next.js front end paired with scheduled crawler clusters (Puppeteer/Playwright with proxy rotation) targeting DIY chains that employ anti-bot systems like Cloudflare or Datadome. The hardest part is deterministic and fuzzy entity resolution (combining EAN matching, LLM classification, and unit-price normalization) to match disparate product listings. This needs ongoing scraping maintenance, proxy budgets, and automated catalog reconciliation pipelines.
