Entreprises

  • Apple - Conseiller support technique

    PARIS 2015 - maintenant

  • CNES - Toulouse - Ingénieur Antennes - Intern

    PARIS 1 2014 - 2014 Configuration of Antennas’ networks for the generation of waves possessing different Orbital Angular Momentum (OAM)

    Paradigm shift in the field of radio-wave communications by means of a new and unexploited degree of freedom: OAM.

    Objective: transmit data on various channels at the same frequency and polarization thanks to the use of the orbital angular momentum of a wave.

    o Setting up of an experiment realized in an adapted anechoic chamber (BCMA CNES)
    o Realization of a prototype allowing us to take advantage of this particular property.

    Modeling tools: Scilab, CST, Test in anechoic chamber.

  • NCTU National Chao Tung University - Ingénieur Recherche - Intern

    2013 - 2013 Internship - NCTU National Chao Tung University - Hsinchu, TAïWAN

    Photonics Laboratory – Project manager: Dir. Han-ping Shieh

    - Conception of an optical multi-user 3D film based on directional sequential backlight system. The auto-stereoscopic display, including lenticular lens, parallax barrier, volumetric display, holographic and light field displays, provides full-resolution 3D images for three observers.

    - Design of a printed circuit card. My work illustrates the method of optimal energy harvesting using piezoelectric transducers embedded in a mat structure. Moreover it describes an approach to harvesting electrical energy from a mechanically excited piezoelectric element by means of vibrations.

  • POLYREY UK Company - Conseiller Relation client - Intern

    2012 - 2012 Intern - POLYREY UK Company – Watford, London

    Tasks:

    - Introduction of a all-new range of products: provided administrative support
    - Assisted customers during transactions & promoted new services
    - Update/chase delegated tasks to ensure progress to deadlines and handle all kind of inquiries within my capacity.

    Polyrey fabrique et développe des stratifiés techniques et décoratifs avec un savoir-faire unique. C'est aujourd'hui une des marques incontournables du design intérieur auprès des architectes, des designers, des agenceurs, des industriels du meuble, de la porte et de la cuisine, reconnue pour la qualité et la créativité de ses produits.

    Au cours ces deux mois j’ai pu fournir une assistance administrative constant au sein de la compagnie. Cela comprend notamment une aide client lors des transactions ou encore la promotion de nouveaux services et d’une nouvelle gamme de produits.
    Sur un plan plus personnel, ce stage m'a permis d'intégrer concrètement une équipe au sein d'une entreprise et d'en découvrir les ficelles. Outre mon intégration au monde professionnel cette première réelle expérience aura également été bénéfique sur le plan linguistique.
