    I developed a website and a browser extension for Athoria's AI Agent. The AI Agent has access to the company's knowledge base and allows for:
    - Streamlining the onboarding of new employees
    - Optimizing the preparation of candidate interviews for recruiters
    - Obtaining a quick analysis matching recruiters' search criteria for a prospect

    The goal of my mission was to transition the existing product from MVP to a marketable product with a more pleasant and intuitive interface.

    My role technically:
    - Development of the messaging with the AI assistant using ReactJS, Tailwind CSS, TanStack Query
    - Use of React Context to separate different functionalities
    - Implementation of unit and integration tests with React Testing Library and Jest

    - The working methodology was Agile Scrum
    - Defining and estimating tasks with the Product Owner
    - Ensuring that the developed designs are adapted to the defined features
    - Regular synchronization with the back-end team regarding front-end needs

    At the end of this mission, the MVP was completely replaced by the new version of the application, with a redesign of components and new functionalities thanks to the complete development of the browser extension.
