Experience

  • FYX SAS
    Co-founder of FYX
    DIGITAL AND IT
    September 2019 - Today (6 years and 9 months)
    Le Plessis-Robinson, France
    Developed by the startup FYX, MyCodex (https://mycodex.io) is a next-generation NoCode BDaaS that allows users to create and manage multimedia databases themselves.
    Thanks to its innovative interface, MyCodex can be used either as a final product for the user, or as a classic database connected to an application layer through a rich library of web services.

    The web agency FYX (https://agencefyx.com/) was created to enhance the MyCodex tool by offering custom, fast, and low-cost developments of web applications such as websites, e-commerce platforms, or SaaS applications.

    As CTO, responsible for Front-End developments, I designed and developed the web layer of the MyCodex application. For this tool, we opted for a full javascript application stack with Node JS for web servers and MongoDB for the database.

  • Armadillo
    Lead Web Developer
    SOFTWARE PUBLISHING
    September 2008 - August 2019 (10 years and 11 months)
    Vanves, France
    Armadillo is an SME specializing in the development of data management applications. Armadillo's specialty is its proprietary NoSQL database with an exclusive proprietary stored procedure programming language.

    Recruited from Haikara, my mission was to support the technical team in implementing the existing Web application for distributing digital documents from the database. This was to analyze the necessary improvements for the second version of the application.
    The technology previously used was entirely proprietary, outdated, and difficult to maintain.
    The new Web application was therefore entirely developed in PHP, then briefly in Symfony, before the third version based on Web Services for greater flexibility in development.
    This latest Full JavaScript version on the client side allowed us to respond to many calls for tenders that were previously impossible for us to fulfill.

    During this period, I supervised the work done by the team on projects and trained new members in javascript, css, and design.

    Not to mention:

    Development of v3 of the full JavaScript Web application;
    Development of v2 of the PHP / JS Web application;
    Creation of mockups, development, and integration of client sites;
    Creation of mockups and integration of the institutional site;
    Configuration of web servers;
    Online payment / e-commerce;
    Video streaming;
    Newsletter integration;
    PDF documentation and diagrams;
    Creation of a FlipBook in Flex;
    JS video sequencer...

    Notable projects:

    The image bank of the BnF;
    The documentation site of the Pasteur Institute;
    The historical iconographic collection of the Indian Ocean;
    The socialist archives of the Jean Jaurès Foundation;
    The collections of the Caen memorial;
    The ENS of Lyon;
    The MACIF brand center;
    The digital library of SIAAP;
    The photo library of the National Archives...
