Numbers as cleared by the owner. Nothing rounded, nothing added.
01
The situation
Dental prices in Poland are public on clinic sites and comparable nowhere. The obvious route, a paid data feed, costs a licence and cannot be verified by the reader.
02
What was built
An owned crawler that reads clinic price lists, a D1 database behind a comparison site, and pages built for search.
Every price on the site links to where it was read, so anyone can check it.
03
What changed
13,690 clinics and 19,541 prices in 497 cities, with no licence bill and a public audit trail for every number.
04
How it runs
Crawling on a schedule, D1, Cloudflare, SEO pages generated from the data.
How the pieces connect
The system on one map. Arrows show what feeds what; hover a piece to light its path.

If you want one of these
Three steps. The six-step version, with the brief and the video request, is on the home page.
01
Scoping call
30 min, free
You describe the situation; I ask three questions and propose a shape.
02
Roadmap and architecture
$1,250 deposit
A written plan with a date. The deposit is credited to the first invoice; the documents are yours either way.
03
Build, handoff, operate
date on the roadmap
One engineer builds every layer on your account, documents it, and can keep operating it.
Questions I get about this
Tap a question. The answer comes back like a text.
Scoping calls · most weeks
A written roadmap and an architecture for your system, delivered after the scoping call. If we build together, the full amount comes off the first invoice. If not, the documents are yours to take to anyone.
You do. The repository, the Cloudflare account, the domains and the data sit under your company from day one. I get access, not ownership.
The roadmap gives you a date before you commit to the build. The stack is small and one person builds every layer, so nothing waits in a queue between departments.
Yes, before you send the brief if you need it. Send yours or use mine.
