FindDoctors Aggregator Server
Finds the earliest public-health appointment in one search instead of one provider at a time, across hospitals and primary-care centres on finddoctors.gov.gr. A Go service ranks results by soonest slot and distance; booking stays on the official portal, and live searches need an authenticated upstream session.
The problem Link to heading
People need to compare availability across provider types and regions without repeating each search manually.
What I built Link to heading
A bounded worker pool searches providers concurrently. The response distinguishes failed checks from empty calendars, and the bundled interface links to the official booking portal. First-time setup still needs an end-to-end user trial.
Implementation Link to heading
- Built a concurrent Go API with bounded fan-out, retries and Prometheus metrics for upstream failures.
- Added a Greek search interface with specialty, location and distance filters, served directly from the Go binary.
- Kept failed availability checks visible with scanOk and a null date, so an outage is not reported as no appointments.
- Documented the session-bridge dependency and deprecated an endpoint whose upstream returned no useful results.
