Can you scrape sites that require a login?

Yes. Authenticated sessions, pagination, and anti-bot protection are the usual case, not the exception.

How do you handle a site that changes its layout?

Monitoring flags a broken run within a day, and maintenance is part of the Run phase, so the pipeline does not silently go stale.

Is web scraping legal?

I focus on publicly available data and respect each site's terms and rate limits. For anything sensitive, we scope it together up front.

All services

Web scraping & data pipelines

Reliable data from any source, on a schedule.

Send a message

If a decision in your business depends on data that lives on someone else's website, I turn that into a reliable feed. Prices, stock, listings, public registers, competitor data: collected, cleaned, deduplicated, and delivered where you need it.

The hard part is rarely fetching a page. It is doing it reliably at scale, behind logins and anti-bot defences, and knowing the moment a source breaks so you never make decisions on stale or wrong numbers.

What you get

A complete dataset instead of a hand-checked sample
Fresh data on a schedule (daily, hourly, or on demand)
Validation and dedup so the numbers can be trusted
Alerts when a source changes or a run fails

Deliverables

Custom scraper with login + anti-bot handling
Normalisation into one clean schema
Output to Google Sheets, Excel, a database, or an API
Scheduling, monitoring, and error notifications
