Rendez-vous Facile

Build a reliable, secure SaaS platform for online appointment management, targeting Moroccan professionals — doctors, lawyers, physiotherapists, notaries — facing high no-show rates and time-consuming manual scheduling.

The technical challenge: design a multi-tenant system capable of serving hundreds of independent practices, each with its own hours, practitioners and rules, while remaining embeddable on existing websites in minutes via a simple widget. The business challenge: convince traditional professions to switch to a digital tool while respecting strict patient data confidentiality (GDPR, professional secrecy).

I architected a scalable Node.js backend (Express, MongoDB) with a documented REST API and a robust JWT authentication system. On the frontend, a reactive React interface offers an interactive drag-and-drop calendar, management of recurring availability slots and exceptional unavailabilities.

The business model relies on three subscription tiers (Solo, Practice, Multi-site) with progressive quotas on practitioner count, monthly bookings and advanced features (automated reminders, statistics, accounting exports). I integrated a Moroccan SMS API for D-1 and H-2 reminders, paired with transactional emails.

A one-line embeddable JavaScript widget for any website, Stripe billing for subscriptions, an analytics dashboard tracking occupancy rates. Cloud hosting with daily backups and encryption of sensitive data.

The platform was adopted by over fifty professionals during its first operational year, mainly across Casablanca, Rabat and Marrakech.

Average 30% reduction in no-shows among customer practices thanks to automated SMS reminders — a direct revenue gain for practitioners. Administrative time cut in half on the secretarial side. The subscription model generates predictable recurring revenue, and the multi-tenant technical base absorbs growth without rework. Several practices upgraded to higher tiers after their first few months of use.
