## The product

Homeowners describe a job, such as a plumber, electrician or cleaner. Verified professionals pay to access leads instead of giving up a commission on the final job. The full flow works end to end on web and in the mobile app: request questionnaire, offers, chat, selection, reviews and an admin verification queue.

## Decisions that matter

- **Personal data stays in the EU.** No personal data goes through US-controlled edge compute; the app is self-hosted on EU servers.
- **Admins can't approve identity checks by hand.** Verification has to pass the automated checks.
- **Rule-based matching first.** Vector matching (pgvector) is ready, but it comes later, once there is real data to learn from. The AI layer is planned on a multi-provider model router with fallbacks.
- **Safe deploys.** CI gates every deploy, and database migrations run behind an advisory lock.

## Stack

One TypeScript codebase. Web is TanStack Start with a Hono API. Mobile is Expo. Zod contracts and design tokens are shared between them. Postgres with PostGIS handles service areas.
