Pratisoins
French marketplace for wellness practitioners — maintainer & fullstack developer
Pratisoins is a French marketplace that connects patients with certified wellness practitioners — reflexology, kinesiology, yoga, shiatsu, hypnotherapy, naturopathy, traditional Chinese medicine, energy practices and more. The platform helps users find a trusted local practitioner near them, browse profiles by specialty, situation (addictions, chronic fatigue, OCD…) or city, and book an appointment either at the practitioner’s office or remotely. On the other side, practitioners get a dedicated pro back-office at pro.pratisoins.fr to manage their visibility, agenda and patients.
I work on Pratisoins as a maintainer and fullstack developer — covering the public website, the pro back-office and the API. One of my main contributions has been optimizing the search by distance using geocoded data, so patients can quickly find the closest practitioners matching their criteria across the Pays de la Loire region (200+ practitioners, 15+ specialties, 50+ cities).

Geo search optimization
The marketplace is built around a find-the-closest-practitioner experience, which means search performance and accuracy directly drive the product. My work on this part includes:
- Storing geocoded coordinates (lat/lng) for every practitioner and city so distance can be computed at query time.
- Implementing distance-based ranking in the search endpoint to return practitioners sorted by proximity to the patient’s location, with optional filters by specialty, situation and modality (in-office or remote).
- Optimizing the underlying SQL queries (indexing + bounding-box pre-filter before the precise distance calculation) so search stays fast as the catalogue grows.
- Exposing clean, paginated results to the frontend so the public site can render city pages, specialty pages and free search consistently.
Other contributions
- Backend maintenance — Prisma schema and migrations (
prisma:generate,prisma:migrate,prisma:concat), bug fixes, dependency updates and troubleshooting migration drift. - API features — endpoints powering the public site (practitioner listings, specialties, situations, cities) and the pro back-office (profiles, agendas, content).
- Pro back-office (pro.pratisoins.fr) — features that let practitioners manage their visibility, appointments and patient interactions.
- Public marketplace — homepage, search, practitioner profile pages, per-city and per-specialty SEO landing pages.
Product surface
- Patient site (pratisoins.fr) — discovery, search and booking.
- Pro back-office (pro.pratisoins.fr) — practitioner dashboard.
- API (api.pratisoins.fr) — REST backend powering both surfaces.
