About Yannick

I am a mobile application developer, specializing in Swift for Apple iOS platforms (iPhone, iPad, Apple Watch) and Flutter, which also allows me to deliver Android applications. I also ensure the design and development of scalable SaaS back-ends, relying on both Node.js / Firebase and other modern stacks: TypeScript / NestJS or Python / FastAPI, REST or GraphQL APIs, SQL and NoSQL databases (PostgreSQL, MongoDB, Redis), as well as major public clouds (Google Cloud, AWS).

  • Consultations 7/7 - Centres Médicaux
    Full-stack Developer: 1 iOS application in Swift (iPhone) with Firebase SaaS Management Interfaces
    MEDICAL
    March 2022 - September 2023 (1 year and 7 months)
    Nice, France
    The software solution includes mobile applications for iPhone, as well as associated management interfaces. It is designed to optimize patient flow management in the waiting rooms of the Azuréens Medical Centers (open 7 days a week). The mobile applications allow patients to register, view, and manage their position in the queue at the medical center of their choice. Management interfaces are available for staff to manage patients and queues, as well as assign consultation and examination rooms to patients and doctors. A higher-level management interface is also provided for a super-administrator or designated person to oversee the operations of each center, including the management of staff and practitioner accounts.

    Problems Solved:Managing real-time queues across all medical centers presented a considerable challenge. Patients can manage their own registrations, while staff also participate in organization, queue management, and the assignment of examination and consultation rooms. Developing these applications in a medical context required particular attention to data security to ensure the protection of sensitive information.
