Doctolib's unprecedented growth in the last 10 years was made possible thanks to pragmatism and avoiding premature optimisation at any cost. In order to keep growing, performance is a critical priority and we are constantly evolving how key features are architected to scale for future needs. Because of this, we are re-architecting our Appointments Management Service. For this service to meet the needs of our Users, high throughput and scalability are crucial. Therefore, we are building this critical service from the ground up leveraging modern event driven, distributed technologies inline with our redefined Technology Strategy. This new Service will help pave the way for a new direction in the way Care Teams manage Appointments, matching Patients with faster access to Care.
