I build scrapers that work: handle pagination, JavaScript-rendered content, rate limiting and anti-bot measures, and output clean structured data. Built to run reliably on a schedule.
Build custom web scrapers that run reliably.
Built scrapers for Cenoskop and Niftycent that extract product data from 500+ e-commerce sites. Handled JavaScript-rendered pages, anti-bot measures, pagination, and output normalization across different site structures. Scrapers run daily and process millions of product pages.
We define the target data and how often it changes, build a scraper with proper error handling, and validate the output. From €1,000 for a first scraper.
Initial scraper implementation. Multiple targets estimated separately.
I build the scraper technically; you're responsible for complying with the target's terms and laws. I structure scrapers to be respectful (rate limits, caching) by default.
I can handle session/auth flows, but you provide valid credentials — I never collect yours.
