About Jean

Web developer in technologies since 2005, I have worked on numerous projects in back and front office, in agencies and client-side (in Paris and its suburbs).

Specializing in PHP/MySQL, I have regularly practiced HTML/CSS/Javascript integration technologies, particularly in AJAX, and I have acquired a certain autonomy in network administration. I specialized for 5 years in Ez Publish CMS projects.

I have also developed personal projects in Ez Publish technology, as well as a CMS prototype that aims to natively limit application caches while maintaining data flexibility to allow for natural adaptation of the tool to business needs.

Freelancer since 2016, I have evolved in various environments and have notably worked with technologies such as Symfony, NodeJS, and Docker.

Outside of work, I have been an amateur musician for many years. I traveled around the world in 2014/2015 with my partner who has since become my wife, and I am the very happy father of a little girl born in November 2019.

I am autumnal, conscientious, and integrate easily into teams. Do not hesitate to contact me for your medium or long-term projects.

    September 2017 - June 2018 (10 months)
    Issy-les-Moulineaux, France
    Team reinforcement for Easybourse, a subsidiary of La Banque Postale group, I participated in the development of the online life insurance financial product.
    This product was implemented in partnership with CNP Assurances, with whom communication is done via a REST architecture constrained by laws and requirements due to the financial nature of the exchanges.
    My work consisted mainly of maintaining the Easybourse website and implementing workflows within a BPM server (Business Process Management) developed in NodeJS technologies to enable asynchronous operation of the relationships between EB servers and CNP servers.
    The EB site is in PHP, based on an internal CMS. It has a service-oriented architecture (with a REST layer for AJAX access).
    The BPM server is in NodeJS technologies, developed in-house, it validates and formats each step of the processes. It communicates with the EB site, a SugarCRM CRM, and the CNP platform via a life insurance analysis and advice website.
    The various development and testing platforms were simulated using Docker.
