Web scraping
at real-business scale.

I run a €500K/year data business in Madrid on scrapers I built. Same code patterns ship to clients on Upwork and direct. Native English, async, fixed-price preferred, no calls.

What I'm known for

  1. Self-healing AI extractors

    20/20 records survive a full DOM scramble. The schema is the contract; CSS selectors aren't.

  2. Anti-bot fluency, named

    Cloudflare, DataDome, PerimeterX. curl_cffi, nodriver, residential rotation — every tool, every tradeoff.

  3. Pipeline-as-product

    State, alerts, observability. Turns one-shot scrapes into $300-1,000/mo retainer pipelines.

  4. Multi-source orchestration

    Parallel fan-out across HN + arXiv + HF + GitHub + PWC, normalized schema, per-source failure isolation.
