  • École Saint Martin
    Development of a Meal Management Application
    EDUCATION AND E-LEARNING
    December 2024 - May 2025 (5 months)
    Mons, Belgium
    In Belgium, the canteen system as we know it in France does not exist. In some schools, meals are provided by an external caterer, and orders are often managed manually:
    • Either through a monthly rental of existing software, which is costly in the long run,
    • Or through paper forms filled out by parents and returned to teachers, with cash or bank transfer payments, requiring time-consuming manual checks.

    It is in this context that I was asked to develop a custom web application to meet the specific needs of schools and families.

    Main features:
    • Parent account creation, adding children, and assigning them to their respective classes,
    • Ordering meals by day, with menu visualization,
    • Online payment via Stripe, secure and traceable,
    • Automatic generation of the weekly meal list to be sent to the caterer,
    • Internal display in the cafeteria for better tracking.

    Technical aspects:
    • Load testing to ensure stability during periods of high usage (back-to-school, end of month, etc.),
    • Architecture optimized for scalability,
    • Design and navigation compliant with RGAA criteria for enhanced accessibility,
    • Implementation of personal data protection (RGPD),
    • Automatic procedure for deleting accounts and sensitive data each summer, at the beginning of the school holidays.

    This project allowed the educational institution to digitize a cumbersome process, reduce manual tasks, and offer parents a smooth, simple, and modern experience.
