Experience

  • Link-up
    Fullstack Development
    EDUCATION AND E-LEARNING
    July 2025 - July 2025
    Paris, France
    Link-up is a company that handles the relationship between learners and tutors to manage educational follow-up.

    It works with several training centers like CRAF2S.

    I worked with both to add a feature for coordinators to evaluate learners individually.

    The feature had to be developed from their administrative panel, so that the training center could create the evaluations, and from the client application, so that the coordinators could evaluate the learners by choosing the evaluation containing the necessary questions.

    Groupe Mobilier Solidaire is a company that sells furniture to its clients.

    What I did for this client is very comprehensive:

    - A showcase/e-commerce website to present their products, collections, catalog, and to place orders.

    - A CRM that handles order management (status changes), creation of products, collections, notifications, addition of media (connected with cloudinary), and all this for each client they have.

    - A very complete backend in Nestjs with a robust architecture that allows managing everything in a quite performant way.
